Abstract: ABSTRACT OF THE DISCLOSURE        A process for producing metallic lead and silver from materials such as ores and concentrates containing the corre-sponding sulfides and particularly a mixture of materials such as galena and tetrahedrite in which process the materials are initially roasted under neutral conditions which include a non-oxidizing or even slightly reducing atmosphere at an elevated temperature for a time equivalent to about 1.5 hours at about 550-600°C. to produce a roasted mineral product in which the roasting causes certain unidentified changes but with the resulting roasted product being more easily leachable so that the process of removing the silver and lead can be greatly simplified.  The leach-ing and separating of the silver and lead includes subjecting the neutral roasted material to a ferric leach such as with an aqueous solution of ferric chloride to convert the lead and silver sulfides to lead and silver chloride, then subjecting the solid residue from this first leaching to a second leaching with aqueous sodium chlorine brine to dissolve these lead and silver salts followed by separating the lead and silver salts from the brine leached material to leave a final solid as a final residue that may be discarded and then separating the lead and then the silver from the filtrate that contains the lead and silver salts.

Abstract: METHOD FOR GENERATING GASES FOR THE REDUCTION OF OXIDE ORES, PARTICULARLY IRON ORES ABSTRACT OF THE DISCLOSURE          In the method, the reduction gases are used in excess relative to the ores to be reduced, a part of the waste gas from the reduction process is re-introduced into the process after cooling thereof, liberation of dust therefrom, and scrubbing of C02 therefrom, another part of the waste gas is discharged and its heat of combustion utilized in the reduction process, and an amount of fresh gas, containing C0 and H2, cor-responding to the amount of spent and discharged waste gas is introduced into the gas circulationcircuit.  The fresh gas is produced by partial oxidation, of hydrocarbons of all types, with oxygen and steamand/or carbon dioxide,and carbon black, C0 and sulfur compounds are washed out, and steam is condensed, before the fresh gas is added to the gas circulation circuit. The mixture of fresh gas and circulating gas is heated to from 800-1000°C by the heat of combustion of the discharged part of the waste gas.  As an alternative, the fresh gas is produced by partial oxidation of sulfur-free methane, methane-containing gases, or natural gas and is introduced, without cooling, to the gas circulation circuit.  Only the recycled gas, after cooling, dust removal and C02 scrubbing, is heated, prior to mixing with the fresh gas, to from 350-550°C, by the heat of combustion of the discharge part of the waste gas.

Abstract: ABSTRACT OF THE DISCLOSURE:          The invention is concerned with an improved method of removing a variable-valency element from sewage water which contains a compound of such element, with concurrent purification of the water, by an oxidation-reduction reaction whereby the variable-valency element of such compound is reduced to a valency that permits precipitation of the element through alkalization, wherein the improvement comprises causing the sewage water to flow through a shortcircuited electrode system containing a cathode and an anode, one of which is electropositive and the other of which is electronegative, in the presence of an effective amount of a compound of an element other than the cathode element and having a more electropositive character than the anode element.  The method of the invention is particularly useful for recovering vanadium from vanadium-containing sewage water originating from gallium-or treatment plants.

Abstract: Abstract of the Disclosure According to this invention floating channels are pro-vided at a certain mutual distance in the floor of the storage place, one end of each channel being connected through an air closure to a main air channel.  The main channel is connected to a source of air under pressure such as a blower at one end there-of.  In their upper part, the floating channels are provided with rectifying fins.  The gaps between the fins are directed to the other end of the rectifying channel, behind which there are provided gates for the bulk material which are mounted in the cir-cumferential wall of the storage place opposite to the main air channel.  Another distribution channel is advantageously provided along this circumferential wall.  It is connected via further air closures and conduits to the individual floating channels at the end opposite to the main channel.  The arrangement according to this invention is neither complicated nor costly, it is reliable in operation, for emptying and aerating, it requires a minimum maintenance, a constant presence of the attendant inside the storage place is not necessary for the operation of the arrange-ment, a constant emptying is possible, the adjustment of the air closures can be advantageously performed outside the storage space in the course of operation of the arrangement and the attendants are not exposed to unfavourable effects of the dusty atmosphere and do not need to enter any close spaces, the hard manual work has been eliminated, a higher utilization of the storage space has been achieved by reduction of the size of the required arrangements built in inside the storage space, all mobile com-ponents of the arrangement are permanently accessible for repair and maintenance and a floor storage place provided with this arrangement can be also used for storage of other materials, for instance of goods in sacks or on pallets.  The pneumatic emptying effect is possible also for larger distances with a high emptying efficiency.

Abstract: ABSTRACT                The present invention relates to a method and apparatus for starting and maintaining a long electrical arc in an arc chamber containing a few atmospheres of pressure of an ionizable gas.  An electrical potential difference is main-tained between two fixed primary electrodes while a short arc is created between the first primary electrode and a pilot electrode, creating ionized gas.  The ionized gas is caused to flow towards the second primary electrode thus creating a region of ionized gas be-tween the two primary electrodes, and hence causing a long arc to be struck.  This method does not require relative electrode move-ment as was the case previously. Such long electrical arcs have utility as sources of heat and light, particularly light of high intensity.
