Characterization and preparation of standard reference materials that contain noble metals: (a) PTA (ores) and (b) PTM (nickel-copper matte)
Authors: McAdam R C , Sutarno R , Moloughney P E
Published: July 2017

Two reference materials containing platinum-group metals have been certified as standards. A concentrate from an alluvial material (containing platinum alloys) from the Tulameen River area of British Columbia has been analyzed for platinum; a nickel-copper matte
from the Sudbury area of Ontario has been analyzed for platinum, palladium, rhodium, and gold. The sample preparation and characterization of the reference materials are described and a statistical evaluation of the "round-robin" analytical values has been performed. These reference standards are
now available from the Mineral Sciences Division, Mines Branch, Department of Energy, Mines and Resources, Ottawa. A program for analyzing the nickel-copper matte for iridium, ruthenium, silver, and, possibly, osmium is to be undertaken. If sufficient satisfactory results are obtained, these
constituents will also be certified for this material.
Mineralogical investigation of some base metal ore deposits and occurrences in the Red Lake mining division, Ontario
Authors: Harris D C
Published: July 2017

Three main types of base-metal sulphide mineralization are present in the Red Lake Mining Division: (1) Small massive copper-lead-zinc deposits occurring mainly in drag folds or shear zones in sequences of metavolcanic and metasedimentary rocks, sometimes
intruded by gabbroic sills and invariably surrounded by granitic rocks. Most of these deposits are located in the belt of volcanic rocks in the Confederation Lake area, 50 miles east of Red Lake, and are typified by the Fredart Lake and South Bay Mines deposits. In the Red Lake area this type of
deposit is represented by the Trout Bay sulphide prospect located on the western limb of the Red Lake basin-like volcanic complex. (2) Low-grade disseminated nickel and copper mineralization as shown by the Trout Bay nickel prospect. The mineralization occurs in an antigorite-tremolite schist
occurring along the stratigraphic top of a chert-magnetite iron formation. The schist represents the sheared and altered basal portion of a metagabbro sill. (3) Massive to disseminated occurrences of galena in carbonate zones cut by numerous quartz stringers and veins. These shear zones are
associated with metavolcanic rocks that have been intruded by quartz prophyry. The Galena Island and Middle Bay prospects are typical of this mode of mineralization.
The polarographic determination of titanium; application to the analysis of lead zirconate lead titanate electronic ceramics
Authors: Hitchen A
Published: July 2017

A polarographic method for the determination of titanium using a 0.5 M ammonium acetate + 0.1 M acetic acid + 0.1 M disodium ethylenediaminetetraacetate (EDTA) supporting electrolyte is described. The titanium polarographic wave is well-defined in this medium.
Relatively few elements interfere, and procedures are suggested to overcome some of those that do. The method has been used to determine titanium in lead zirconate-lead titanate ceramic powders and solutions. The results compare favourably with results obtained by a differential spectrophotometric
method.

Refractory-grade magnesia in Canada
Authors: Palfreyman M
Published: July 2017

The increasing demand for magnesia refractories is a direct result of the increasing use of the basic oxygen furnace in the steel industry. This trend may be expected to continue, at least until the open-hearth furnace has been phased out. At the same time, the
specifications for refractory-grade magnesia are becoming more rigid, particularly with respect to iron oxide and to boron, which is present in seawater magnesia. As a result, more interest is being shown in the beneficiation of natural magnesitic ores to produce high-purity magnesia free from boron
and very low in iron oxide. This bulletin discusses the properties of refractorygrade magnesia, reviews the magnesia industry in Canada both past and present, and lists known Canadian sources of magnesitic rock.
Leaching of uranium from Elliot Lake ore in the presence of bacteria
Authors: Harrison V F , Gow W A
Published: July 2017

Testing by the Departments of Mines and Technical Surveys and of Agriculture showed that mine water and slope ore from Denison Mines contained bacteria belonging to the Ferrobacillus-Thiobacillus group. Percolation leach tests showed that the bacteria promote the
production of an acid-oxidizing solution effective in leaching, whereas in the absence of bacteria no leaching of the uranium occurred
Stable copper cyanide plating baths
Authors: Dingley W , Bednar J , Rogers R R
Published: July 2017

Stable copper cyanide plating baths which can be operated at 25C (77F) have been developed. These conform to both of the following relationships: (1) OH- normality "free" CN- normality, and total NaCN normality . (2) varies between 2.6 and 2.9, depending on the
bath concentration. Cu normality Advantages of these baths include: (1) comparatively simple control of bath compositions. (2) improvement in the nature and adhesion of the copper deposits, and in the plating cell operating conditions. (3) ability to use higher cathode current densities. (4) ability
to copper plate high strength steel such as Type 4037 without embrittling the steel. (5) ability to plate comparatively thick copper coatings directly on steel without the use of a "strike" bath.
Sulfurous acid corrosion of low carbon steel at ordinary temperatures - i. its nature
Authors: McLeod W , Rogers R R
Published: July 2017

Corrosion rate data are presented for low carbon steel in (1) a combination of sulfur dioxide, water vapor and air, and (2) aqueous solutions of sulfurous acid in the absence of air, at ordinary temperature. Information as to the nature of the corrosion products
is presented and it is shown that this depends on the place in which the corrosion takes place to an important extent
Instrumentation in the cyanidation process
Authors: Gow W A , McCreedy H H , Kelly F J
Published: July 2017

It is believed that many of the problems encountered in the operation of gold cyanidation plants are difficult to resolve due to the lack of sufficient and reliable information regarding the variations and actual values of operating variables at any given time.
The application of instruments to monitor the more important variables in the cyanidation process should result in more efficient plant operation and a better understanding of the process. The use of pH and conductivity sensing devices for alkalinity measurements , a monitor to determine the
dissolved oxygen content of plant solutions, a continuous cyanide titrator and sonic control of grinding circuits are discussed. Although the discussion is oriented toward the cyanide process, much of the paper is applicable to other ore treatment operations.

The production of niobium oxide from pyrochlore-perovskite concentrate
Authors: Kelly F J , Gow W A
Published: July 2017

A chemical process, based on laboratory investigations, is proposed for the production of high-purity niobium oxide from a pyrochlore-perovskite flotation concentrate produced from ore obtained at the Oka, Quebec, property of Columbium Mining Products Limited.
The method developed included the decomposition and dissolution of the flotation concentrate with hot, concentrated sulphuric acid. The dissolved niobium was purified and concentrated by a solvent extraction step, using methyl isobutyl ketone as the extractant. The niobium was recovered from the
extractant with ammonium fluoride solution from which niobium oxide was precipitated with ammonia. Finally- , the filtered and washed precipitate was calcined. Ninety-six per cent of the niobium was recovered in a product analysing 99.9 per cent Nb 204 . The reagent cost was in the range of $1.00 to
$1.25 per pound of niobium recovered.
The analysis of the viscous property of rocks for classification
Authors: Parsons R C , Hedley G F
Published: July 2017

The tim?,-dependent deformation of geological materials can be thought of in terms of classical rheological models. The viscous component though usually present, may not be of sufficient magnitude to measure over the limited time spans available. For rock
classification purposes, several specimens fromeach of twenty different rock types have been tested in uniaxial compression to determine the magnitude of the viscous component. Several methods of evaluating the results to determine the magnitude of the viscous coefficients are discussed and
compared. Two basic methods use extrapolation or the shape of the time-deformation curves. It is found that for the great majority of the rock types tested, the semi-log relationship, log time vs. strain, closely fits the data. Extrapolation to the region of 200 min gives a realistic value of the
strain rate. The strain rate of 2 in/in/hr appears to be a practical value for the division between elastic and viscous behaviour of the rock substance.
Control of oil-ash slagging by an additive
Authors: Lee G K , Mitchell E R
Published: July 2017

Conventional cleaning methods were found to be inadequate for removing slag deposits from high-temperature heat-transfer surfaces of oil-fired boilers. The research project described in this paper first established that minute interconnecting voids in slag
deposits were sufficiently large to allow penetration by water treated with a suitable surfactant. From this was dev eloped a practical water washing procedure that has been adopted as routine maintenance in certain marine boilers. Subsequently, fundamental combustion studies established that the
mechanism of deposition for indigenous oil-ash constituents is primarily one of molecular diffusion. This finding indicates that new and radical burner and boiler design concepts are needed to overcome operational problems when untreated high-vanadium fuel oils are burned. Also described is a
program of research on fuel oil additives to alleviate the superheater slagging problem. This includes the evaluation of many additive materials in a laboratory combustion rig and the development of a particular magnesia-alumina formulation that has promise as a practical and effective additive.
Several large power utility boilers are now operating regularly on additive formulations developed through this research program, and preliminary reports indicate a high degree of success.
Practical problems in particle size and surface area measurements
Authors: Winer A A , Wright I F
Published: July 2017

Different techniques for particle size measurement employ different physical principles, and therefore may well show different results. Some methods used in practice are compared and discussed. Variations in the test results may also be due to material
characteristics, such as porosity, surface activity' and the tendency of some finely divided powders to agglomerate. These may require additional analytical techniques, such as surface area measurement by gas adsorption. A relatively simple and rapid surface area technique is
discussed.
Ore deposits of the cobalt area
Authors: Petruk W
Published: July 2017

The Cobalt area is underlain by Keewatin volcanic and sedimentary rocks, pre-Algoman intrusive rocks, Algoman granite, Huronian sediments, Nipissing diabase, and late Keweenawan diabase dykes. Silver deposits occur as individual veins and clusters of veins in
Keewatin rocks, pre-Algoman lamprophyre dykes, Huronian sediments, and Nipissing diabase. The veins are generally nearly vertical and are up to several hundred feet in vertical and horizontal extent. They are composed of carbonate minerals and contain shoots of silver ore, cobalt arsenides, and
nickel arsenides. The silver ore shoots contain up to 8,000 ounces silver per ton of vein material. The silver in them is present as masses, veinlets, and separate grains. The masses and separate grains occur in arsenides, carbonate veins, and adjacent .wall rock; the veinlets occur in fractures in
the veins and wall rock, and along the boundaries between the veins and wall rock.

The origin of pleochroism in erythrite
Authors: Faye G H , Nickel E H
Published: July 2017

Optical absorption measurements show that the pleochroism of erythrite is due to variations in the main absorption envelope in the 400 to 600-mn region as crystallographically oriented sections are rotated in linearly polarized light. The absorption envelope
arises from the 4T1 (F) --> 4 T, (P) transition, with contributions from transitions derived from 2G and 'H levels, in octahedrally coordinated Coil- ions, of which there are two kinds (Coi and Con) in erythrite. The pleochroism is related to the interaction of the electric vector of
light with electrons located in specific t2g orbital lobes of ions in the Coi and Coil sites. The validity of the present interpretation rests on the assumptions that erythrite is isostructural with vivianite and symplesite and that the principal optical directions are essentially coincident with
the "molecular axes" of the Co2+-bearing octahedra.
Structural stability of minerals with the pyrite, marcasite, arsenopyrite and lollingite structures
Authors: Nickel E H
Published: July 2017

The structural stabilities of the disulphides, diarsenides and sulpharsenides of iron, cobalt and nickel are explained on the basis of ligand field theory. The structural stabilities can be correlated with the number of non-bonding d electrons of the metal atom
in the structure, and can be explained by the tendency of the compounds to form structures in which maximum electron spin-pairing takes place. The pyrite structure, which is favoured by metals with six or more non-bonding d electrons, and which includes pyrite, cattierite, vaesite, cobaltite and
gersdorffite, is characterized by metal-sulphur octahedra joined at corners, with no apparent interaction between the d electrons of neighbouring metal atoms. The other structures are all characterized by shared octahedral edges along one direction, so that the metal atoms are brought into
relatively close proximity. In the marcasite structure, which includes marcasite and rammelsbergite, both with six non-bonding d electrons, the metal atoms repel each other because of completely filled t 2, levels. ln the arsenopyrite structure, which includes arsenopyrite and safflorite, both of
which have live d electrons that do not participate in metal-sulphur bonding, pairs of metals are drawn together to permit spinpairing of the odd electrons. ln lollingite, in which the iron atom is assumed to have four non-bonding d electrons, the d orbitals in the c crystallographic direction are
emptied, permitting close iron-iron approaches in this direction, as well as complete spin-pairing of the electrons in the two remaining t 2 , orbitals.
Lead zirconate-lead titanate piezoelectric ceramics with iron oxide additions
Authors: Weston T B , Webster A H , McNamara V M
Published: July 2017

An investigation of the effects of small additions of Fe203 to lead zirconate-lead titanate ceramics with compositions between 45 and 60 mol% lead zirconate has shown that, with 2 moles of Pb0 to balance each mole of Fe303, the solubility of Fe.O3 was about
0.8 wt% in compositions near the tetragonal-rhombohedral boundary. The dielectric constant and dissipation factor for both rhombohedral and tetragonal materials were decreased by addition of iron oxide, whereas the mechanical quality factor and frequency constant were increased. The dependence
of the electromechanical properties on grain size was qualitatively similar for both undoped and iron oxide-doped materials; the presence of iron oxide inhibited grain growth and lowered the limiting grain size below which the electromechanical properties change rapidly with grain
size.
Improved silver cyanide plating baths: laboratory development
Authors: Dingley W , Bednar J , Rogers R R
Published: July 2017

Improved silver plating results were obtained during laboratory experiments in which the bath constituents were related to one another as follows: (1) Y = 0.374 -I- 0.768X 0.178X2 Y = OH - normality where and X "free" CN normality total NaÇN normality (2)
is between 6.1 and 8.1 Ag normality (the exact value depending on the bath composition) The advantages of these improved silver plating baths include: low rate of cyanide consumption and carbonate formation; high current efficiency and low cell voltage when operating at comparatively high cathode
current density; deposition of uniform fine, in the absence of brighteners; insolubility of the silver anodes in the grainedeposits plating bath when the latter is not in use; absence of silver deposition on unconnected steel cathodes immersed in the plating bath; ability to plate satisfactory
silver deposits directly on steel; ability to plate high strength steels, such as Types 1062 and 4037, directly with silver without embrittling the steels

Variations in the ceramic and magnetic properties of barium hexaferrite samples made from iron oxides prepared by different methods
Authors: Bowman W S , Alexander G E , Jaworski J M , Ingham G A
Published: July 2017

Physico-chemical properties of iron oxides produced by two different methods and the ceramic and magnetic properties of unoriented and oriented barium hexaferrite specimens prepared from these oxides are presented. The influence of calcination temperature on the
grain growth of the polycrystalline barium hexaferrite during subsequent sintering is shown. Differences found in the reactivity, grain growth and magnetic properties suggest the use of different technological procedures for the production of barium ferrite from different iron
oxides
The application of dark-field electron microscopy to the determination of crystallite size in ferrites
Authors: Smith E
Published: July 2017

Barium and strontium ferrites were prepared by co-precipitation from nitrate solutions, filtering and calcining at 1100°C or 1300°C. The calcined powders were ground in a steel mortar. A method was developed for supporting the powders in thin plastic
films for electron microscopy. Powders were examined by electron microscopy in bright and dark fields, and by electron diffraction. Three types of particle in the micron range of size were found, two being monocrystalline and one finely polycrystalline with a crystallite size of about 500À. It
was not possible to distinguish between these particles without the use of electron diffraction. It was found that the grains of the barium ferrites were generally smaller than those of the strontium ferrites prepared under similar conditions, and that the grain sizes of both increased with
calcining temperature.
Iron-iron interaction in iron-containing zinc sulphide
Authors: Keys J D , Horwood J L , Baleshta T M , Cabri L J , Harris D
C
Published: July 2017

The behaviour of iron in ZnS has been studied through the effect of iron concentration on magnetic and electrical properties. Specimens containing iron in amounts varying from 0.09 to 16.16 atom per cent have been synthesized. These were found to be homogeneous
by electron-probe microanalysis and under the reflecting microscope. At lower iron concentrations the synthetic and natural iron-bearing sphalerites are paramagnetic and their magnetic susceptibilities vary with the iron content in a linear manner. At higher iron concentrations these iron-bearing
sphalerites become increasingly antiferromagnetic and their magnetic susceptibilities vary in a non-linear manner. The antiferromagnetic behaviour may be comparable to that observed in Mn-bearing ZnS and is probably the result of similar magnetic ordering of the substitutional iron. Electrical
conduction for a natural iron-bearing sphalerite has been found to result from migration of low-mobility holes rather than by electrons. This observation is consistent with the mechanism known as d-band conduction, which attributes electrical current to the flow of holes in the d-bands of transition
metals. This type of conduction is possible in iron-containing ZnS through the interaction of Fe+ with Fe2+, with the Fe3+ in either the tetrahedral or the octahedral position.

Analysis of total sulphur in Canadian coals by a modified oxygen-flask method using Arsenazo (iii)
Authors: Ahmed S M , Whaley B J P
Published: July 2017

A modified oxygen-flask method for total sulphur analysis using Arsenazo (Ill) as titration indicator and Chromel 'A' wire as combustion-grate material has been used to analyse twelve Canadian coals of widely differing rank, ash, and sulphur content. The results
indicate that the method is generally applicable to coal sulphur analysis. The endpoint unlike that of Thorin is sufficiently definite to permit use of the method by relatively untrained analysts. The precision of the method appears to be similar to that of the Eschka method
Low NOx combustion: the effect of external flue gas recirculation on emissions from crude oil combustion
Authors: Brown T D
Published: July 2017

The initial results are presented from a continuing investigation of the production of nitric oxide (NO) during the combustion of two liquid fuels in a pilot-scale 16-gph (US) boiler. Low-excess-air combustion is shown to be less effective than flue-gas
recirculation in reducing the NO emission. The emission of (NO)t in g/kg fuel can be related to the recirculation ratio, R, and of the emission without recirculation (NO)tt by a general linear equation : (NO)t = 1-AR (NO)++ At the two combustion intensities used in the experiments described in this
paper, A is independent of the excess air level at the higher combustion intensity but is dependent on the excess air level at the lower combustion intensity.
Application of a new method for the calculation of force constants
Authors: Gillieson A H
Published: July 2017

A method is presented which permits calculation by means of a digital computer, of a complete set of force constants, using only the vibrational frequencies and the geometry of a molecule. The eigenvalues containing the vibration.al frequencies are connected with
the force constant matrix by the CAYLEY-HAMILTON theorem. This is resolved by the NEWTON method. As a first approximation the normal vibrations are assumed to be completely uncoupled. Then the known interactions of the kinetic energy are introduced stepwise and so a set of force constants is
obtained which contains all the interaction terms of the potential energy.
Forgeability of steels: a critical survey of the literature

The use of low and high alloy steels is expanding considerably. The fabrication procedures for such alloys are becoming more complex. An attempt is made, in this report, to describe the effect of alloying elements on the hot-workability aspect .of the
fabrication of steels, and to indicate how changes in the forgeability characteristics may be predicted by laboratory tests. The different types of tests used and their limitations are discussed. Work which may be done to extend the use of these laboratory tests and to obtain more consistent and
reliable results is outlined. A comprehensive list of references and a series of illustrative graphs con-iplete the report.
Review and evaluation of methods of particle size analysis. Part i: the definition of terms and classification of sizing methods; part ii: sieve analysis.
Authors: Pilgrim R F
Published: July 2017

Part I is intended as a general introduction to the study of methods of particle size analysis. Included are definitions of the terms "particle size" and "particle shape", methods of measuring shape factors and correlation factors (i. e. factors relating the size
of particles measured by different methods), and a classification of sizing methods to provide an orderly framework for this study. Part II, on sieve analysis, is divided into three chapters. The first is concerned with the structural characteristics of sieves, the various sieve series and standard
specifications, and methods of certifying sieves dimensionally. The necessarily wide tolerances on sieving cloth permitted by standard specifications provide a logical basis for the detailed study of sieve standardization methods in the second chapter. The third chapter deals with the mechanics of
sieving, i.e. the way in which sieves are used in size analysis and the various factors which affect the accuracy of sieve analyses. Sieving is shown to be a statistical process, the probability of a particle passing through a sieve depending on several factors. Each of these is discussed in some
detail to show, for example, the advantages of using wet sieving and a rate-defined sieving end-point.

Present status of underground storage of natural gas in southern Ontario and Quebec
Authors: Charbonnier R P
Published: July 2017

Following the completion of the Trans-Canada gas pipeline in 1958, the consumption of natural gas is expected to grow very rapidly in southern Ontario and Quebec -- in a trend similar to that which has occurred in the eastern United States in recent years. The
United States data show the importance of underground storage of natural gas as a solution to irregular consumption problems and winter peak demand periods. The situation in Canada is likely to be very similar. In the present study various aspects of underground gas storage are considered, including
an example of evaluation of market requirements in southern Ontario, a survey of the design and operation of partly depleted fields and aquifer reservoirs, and some cost data. The present facilities and future possibilities of gas storage in southern Ontario and Quebec are also studied, and show the
desirability of further investigations of the storage gas pool possibilities in that area.

Stockage souterrain du gaz naturel dans le sud de l'Ontario et du Québec
Authors: Charbonnier R P
Published: July 2017

Après l'achèvement récent du gazoduc transcanadien, la consommation de gaz naturel devrait s'accroître très rapidement dans le Sud de l'Ontario et du Québec, tout comme la chose s'est produite ces dernières années dans
l'Est des États-Unis. Les données relatives aux États-Unis démontrent l'importance du stockage souterrain du gaz naturel à titre de solution aux problèmes que posent la consommation irrégulière et les périodes de pointe en hiver. La situation est
probablement analogue au Canada. Là présente étude tient compte des divers aspects du stockage souterrain du gaz; elle comprend un exemple de l'évaluation des besoins du marché dans le Sud ontarien, un examen de l'agencement et de l'utilisation de champs partiellement
épuisés et de réservoirs aquifères, de même que certaines données quant aux coûts. Les réservoirs actuellement utilisés et d'autres que on pourrait utiliser à l'avenir pour y stocker du gaz dans le Sud de l'Ontario et du Québec donnent
également lieu à un examen, et l'auteur montre qu'il est souhaitable de poursuivre les recherches relativement aux endroits où l'on pourrait stocker du gaz dans la région en cause.

Air pollution: causes and control
Authors: Whaley H , Friedrich F D , Lee G K , Mitchell E R
Published: July 2017

The Mines Branch is engaged in a dual program of controlling combustion-source air pollution. The first is an extensive combustion research program in which pollutant formation in flam.es is minimized and followed by the chemical neutralization, so far as
possible, of sulphur dioxide (SO2), sulphur trioxide (SO ), nitrogen oxides (NOx), and acid soot. The effectiveness of efficient combustion and an additive for residual fuel oil are described. The second program is one of controlling ground-level concentrations of combustion gases by recommending
the chimney height necessary for adequate dispersion. To do this, an empirical plume-rise equation was developed as, a sound basis for the CCRL (Canadian Combustion Research Laboratory) dispersion standard which is discussed and presented in graphical form.

Authors: Ritcey G M
Published: July 2017

The subject of solution purification using ion exchange or solvent extraction as techniques in hydrometallurgical processing is described. No attempt has been made to cover the many theoretical aspects, but rather to provide an adequate background of information
and references useful to those contemplating industrial processing. Among the items covered are the techniques, reagents, equipment, processing costs, and selected extraction systems.
Non-ferrous metals casting, history and forecast
Authors: Meier J W
Published: July 2017

The history of non-ferrous metals casting is reviewed, tracing the art of founding since the fifth millennium BC and illustrating the excellent achievements of early civilizations in moulding and casting. Ancient metallurgy was born in the Middle East and spread
very early throughout Europe, the Far East and Africa. Independently, the art of casting was discovered by the pre-Columbian Indians in Middle and South America. ln Europe, the peak of artistic casting development was reached in Classical Greece. After the Middle Ages, when founding was confined
mainly to the production of bells, guns and ornamental castings, came the Renaissance and the splendid castings of Cellini and other artist-founders. The coming of the Industrial Age and the discovery of new metals, especially aluminum, magnesium, nickel and zinc, considerably increased the output
of castings. The concept 'of internal casting quality was introduced and with it the need for adequate mechanical properties for proper performance. A brief account of present trends in "premium-quality" castings and some recent improvements in casting techniques is included. Considerations of the
future of non-ferrous metals are based on statistical surveys of growth figures of world outputs analyzed by geographical distribution, volume versus weight, price and per capita consumption. United States casting production figures illustrate the trend of shifting from sand casting to die casting.
The future of the non-ferrous castings industry depends on the consistent production of highest-quality castings, which can compete with wrought products and other competitive materials, as well as on further automation and mechanization of all foundry equipment and procedures, using mechanical
robots and modern computers.

Authors: Tibbetts T E , O'Brien D J
Published: July 2017

Physical and chemical analyses of seventy-seven coal samples are reported representing the eleven operating mines in Nova Scotia and six operating mines in New Brunswick. The samples were taken and analysed by the Fuels Research Centre during the year 1969. They
represent the production on a specified day of the coals as commercially prepared at the mine or the coals as delivered to thermal electric generating stations.
Desulphurizing gases with mgo - recovery of concentrated so2 or elemental sulphur
Authors: Marler P , Ingraham T R
Published: July 2017

Finely divided MgO-Fe2 03 mixtures were supported on a Liber pad and used at 825°C to remove SO2 from dilute gas streams. The reaction has an activation energy of about 24 kcal/mole and produces only MgSO4 The efficiency of mgs04 formation varies with the
partial pressure of oxygen in the gas, the ratio of the amount of MgO to fiber, and the linear flow rate of the gases. MgSO4 may be decomposed to MgO readily by decreasing the partial pressure of oxygen in the gas. When the partial pressure is moderately decreased with added CO, concentrated SO2 is
evolved. When an excess of CO is used, COS is evolved. The COS may be converted readily to sulphur by the addition of SO2 in a second step. The activity of MgO does not decrease with repeated recycling.

The spectrophotometric determination of uranium in ores, residues and other materials
Authors: Ashbrook A W
Published: July 2017

A spectrophotometric method, reported by Johnson and Florence, has been used for the determination of uranium in ores, residues, and other materials. The method makes use of the very sensitive chromogenic reagent 2-(5-bromo-2-pyridylazo)-5-diethylaminophenol
(Br-PADAP) which gives a red complex with uranium at pH 7.6 for which X max - 578 nm. In the presence of a complexing solution containing (1,2-cyclohexylenedinitrilo)-tetraacetic acid (CyDTA), sulphosalicylic acid, and sodium fluoride, the only serious interference is caused by chromium (III),
vanadium (V), and phosphate. By extraction of uranium into tri-n-octylphosphine oxide (TOPO)-cyclohexane solution the method becomes highly specific for uranium. A number of diverse uranium-containing materials have been analysed for uranium by this method l and the results are reported here.
Comparison is made with results obtained by fluorimetric, X-ray fluorescence, and volumetric methods.
Evaluation of Canadian commercial coals: Alberta and British Columbia - 1970
Authors: Tibbetts T E , Montgomery W J
Published: July 2017

The physical and chemical analyses of thirty-four coal samples are reported. In addition, the chemical analyses of ash of most of the same coals are reported in a separate section. The samples were taken and analyzed by the Mines Branch during the year 1970. They
represent the production on a specified day of the coals as commercially prepared at the mine or, referring to the channel samples, the coal seam where mining was in progress or planned. Coals from thirteen mining operations in two of the three coal mining provinces of western Canada, Alberta and
British Columbia, are represented; they include subbituminous and bituminous coals.
Fuel consumption and air pollution trends in Canada 1965 - 1980
Authors: Mitchell E R
Published: July 2017

A projection of fuel consumption to 1980 anticipates a continued strong growth rate of 6.57e per annum. Thus, it is possible that fuel consumption in 1980 will be 48.9 million tons of coal, 35.5 million of which will be needed for electric power generation, 796.5
million barrels of liquid fuels, and 2.5 trillion cubic feet of natural gas. In describing the impact of the resulting pollution on the air environment, the paper shows that, by applying technically feasible abatement measures in 1975, about 6.9 million net tons of harmful pollution can be avoided
in 1980. This reduction would be larger if, after 1970, more coal burning were not projected for thermal power generation. Despite this, the 1980 pollution burden will be 33% below the 1970 level. After 1980, the pollution burden will increase with population growth and, all things remaining
equal, the 1970 level of pollution will return in the year 2004. To accomplish this significant feat, it is roughly estimated that a capital expenditure of $1.6 billion will be needed by 1980 plus $300 million per year for automobile pollution control devices starting in 1975. Despite this large
expenditure the paper indicates that, in 1980: (1) the air environment will appear dirtier in the regions where coal is burned for power generation (see Appendix I, item 1), because of a 151% increase in particulate emissions even with efficient electrostatic precipitators, but cleaner in the
vicinity of steel mills and mineral processes where dust collectors are being installed; (2) odours from oil refineries, paper mills and other processes will continue but (3) the air will be more pleasant to breathe, and maybe healthier, in urban areas.
