Title: Improvements relating to the recovery of lead compounds
IPC: C01G21/00
Filed: 1921-11-28
Abstract: Ores &c. containing lead preferably containing or with addition of oxidizable sulphur are treated in the presence of dissolved chlorides with chlorine or hypochlorites at a low temperature until the lead is converted into tetrachloride and dissolved. Silver chloride remains with the residue and may be extracted with the sulphate.  The solution is separated and the surplus chlorine is blown out or reduced by reducing agents to obtain lead chloride, or sulphate, or the solution is neutralized or rendered alkaline to obtain the lead as peroxide.  After the separation of the lead the copper may be removed by cementation or electrolytically and the zinc electrolytically or by precipitation as hydroxide with lime.  When the lead has been precipitated as dichloride, arsenic may be precipitated previous to the separation of the copper, by oxidizing (if the solution has been reduced) to convert the iron into the ferric state and neutralizing for instance with a carbonate such as limestone or roasted copper pyrites or both.  Carbonate ores may also be leached with the acid liquor to neutralize the liquor and extract ingredients from the ores.  The reducing agents mentioned are wastes containing zinc or iron, oxidizable salts such as ferrous salts, sulphurous acid or its salts, sulphuretted hydrogen, sulphides, thiosulphates, or organic reducing agents such as sulphite cellulose waste liquor.  When sulphurous acid is used the lead is precipitated as sulphate.

Title: Aerating apparatus and method particularly for froth flotation processes
Inventor: DAMAN ARTHUR CHESTER
IPC: B03D1/16
Filed: 1952-12-18
Abstract: 757,698. Aerating pulp; froth flotations. MINING PROCESS & PATENT CO. Dec. 18, 1952, No. 32140/52. Classes 82(2) and 86. A method of aerating a body of pulp of substantial depth in a confined treatment zone subject to continuous feed and discharge, more especially for froth flotation treatment, includes the steps of subjecting the pulp in a lower portion of the zone to a centrifugally induced flow, during which agitation and aeration of the pulp and a beating of the aerated pulp causing it to rise in the zone is effected, and subjecting a portion of the thus aerated pulp in an upper portion of the zone to a centrifugally induced flow during which further aeration and agitation of the said portion of the pulp is effected. Known froth-flotation reagents are used. In Fig. 1, the centrifugal circulation in the lower part of the zone C is induced by a rotary squirrel cage impeller R on a rotary shaft 18 having air ducts 47. The pulp is circulated through openings 49, 51 in the bottom and top discs 45, 44 of the impeller R is agitated and aerated by the action of the squirrel cage bars, 46, and the aerated pulp is subject to a beating action by the bars 43 of a stationary enclosure E. Pulp which is not sufficiently aerated to float to the surface is recirculated for further aeration and agitation by a rotary impeller 37 mounted on the shaft 18 which draws such pulp through holes 41 in a hollow column 33 which carries a stationary hood 35 carrying vanes 36 surrounding the impeller 37. The aerating gas is supplied to the hollow shaft 18, and to the hollow column 33 from a header 28. The bars of the squirrel cage rotor may be inclined, Figs. 5-10 (not shown) in order to impart to the pulp, components of movement in an upward, or in an upward and downward direction. Several impellers in series may be provided in a single tank T, the flow of pulp through the tank from an inlet 22 to an outlet 23 being controlled by inclined partitions 54 and transverse partitions 55. In a modification, Fig. 3, also having a squirrel cage lower impeller R<SP>1</SP>, the upper impeller consists of upper and lower rotary members 86, 87 separated by a stationary partition 85 the upper member having openings 88 through which the recirculated aerated pulp is drawn into the impeller. In a further modification, Fig. 4, the upper and lower impellers are part of a single unit which is divided by a centrally apertured partition member, which may be a stationary partition 138 or may be a partition 148 formed integrally with the impeller unit. The bore in the impeller shaft may extend through the lower end of the shaft as shown in Figs. 1 and 4 whereby aerating gas is discharged between the bottom of the lower impeller and the bottom of the tank for admixture with pulp entering the lower impeller.

Title: Lubricating greases
Filed: 1948-12-14
Abstract: A lubricating grease, especially suitable for high temperature lubrication, comprises 60-95 per cent by weight of a lubricating oil, 3-30 per cent of an alkali metal soap of fatty acids having 12-22 carbon atoms in the molecule 0.1-10 per cent of an alkali metal salt of a monocarboxylic acid having 1-5 carbon atoms in the molecule and 1-8 per cent of a vegetable wax.  The lubricating oil is preferably mineral oil, while the soap may be an alkali metal soap of oleic or stearic acid, particularly sodium or lithium oleate or stearate.  The alkali metal salt of a monocarboxylic acid having 1-5 carbon atoms in the molecule is preferably an alkali metal acetate or formate, particularly sodium or lithium acetate.  These salts may be added as such to the grease compositions, or the corresponding acids may be added, provided there is sufficient alkali in the grease composition to neutralize these acids and to saponify the fatty acids. Alternatively, the alkali metal salts of monocarboxylic acids having 1-5 carbon atoms in the molecule are incorporated in the grease composition by mixing glycerin with the rest of the grease-forming components before the grease is cooked, so that these salts are formed in situ by decomposition of the glycerin.  Vegetable waxes which may be employed are candelilla, carnauba, bayberry and Japan waxes. These waxes are employed as soap-dispersing agents and the grease composition may contain montan wax or an oil-soluble metal petroleum sulphonate, particularly sodium petroleum sulphonate, as an additional soap-dispersing agent.  In the examples, grease compositions are prepared from mixtures of (1) oleic acid or hydrogenated menhaden oil fatty acids, acetic acid, sodium hydroxide, mineral lubriating oil and candelilla wax or (2) stearic acid, acetic acid, lithium hydroxide monohydrate, mineral lubricating oil and candelilla wax.  For comparison purposes, similar compositions are described from which the candelilla wax has been omitted. Specification 643,536 is referred to.  The Specification as open to inspection under Sect. 91, refers to grease compositions comprising an alkali metal soap of a fatty acid having 12-22 carbon atoms in the molecule and 0.1-10 per cent by weight of a saturated monocarboxylic acid having 1-5 carbon atoms in the molecule or of a compound, such as glycerin or a glyceride, which when heated in the presence of excess caustic alkali decomposes to produce such acids.  In an example, a grease composition is prepared from a mixture of oleic acid, sodium hydroxide, mineral lubricating oil and glycerin.  For comparison purposes, a grease composition is described which is prepared from a mixture of oleic acid, sodium hydroxide and mineral lubricating oil; an excess of sodium hydroxide is employed and the mixture is cooked until the excess is reduced to 1 per cent.  The resulting grease contains sodium carbonate.  This subject-matter does not appear in the Specification as accepted.

Title: Improvements in or relating to the manufacture of alkyl chlorides
IPC: C07C17/08
Filed: 1935-11-22
Abstract: Alkyl chlorides are produced by passing an olefine and hydrogen chloride into a suitable liquid medium containing a catalyst such as aluminium, ferric, or zirconium chloride or antimony pentachloride at a temperature such that the alkyl chloride escapes in the vapour phase.  The liquid medium must be inert to the catalyst and have a boiling point above that of the alkyl chloride; thus when aluminium chloride is the catalyst polar solvents such as alcohols and ethers, and also aromatic and some other cyclic compounds such as cyclohexane are not suitable as the alkyl chloride would then react with such liquids.  Suitable liquids are chlorinated hydrocarbons such as b -trichlorethane, symmetrical tetrachlorethane, carbon tetrachloride, ethylene dichloride and a dichlorpropane, and aliphatic hydrocarbons. The pressure may be atmospheric or higher or lower.  In examples, (1) ethylene and hydrogen chloride are passed into b -trichlorethane containing aluminium chloride at 42--60 DEG  C; and (2) propylene and hydrogen chloride are passed into b -trichlorethane containing ferric chloride.
