摘要： A method of recovering both brass and zinc from metallurgical residue containing those metals and including slag containing zinc oxide, comprising charging the residue into a furnace, in such furnace heating the residue up to about 1,250* C., the brass which is molten at said temperature sinking to the bottom of the furnace, adding carbon reducing zinc oxide in the slag to zinc metal in vapor form, withdrawing and condensing the zinc vapor, tapping the molten slag from the furnace and tapping the molten brass from the furnace. Flux may be and normally is added to the residue to render the slag more fluid although under certain conditions addition of flux may be unnecessary. When flux is added it may comprise at least one of lime, silica, scrap glass, borax, rasorite and colemanite. The carbon reductant may comprise at least one of metallurgical coke, petroleum coke, bituminous coal, anthracite coal and graphite. The zinc vapor is withdrawn from the furnace through a first outlet passage, the slag after at least the greater portion of the zinc oxide therein has been reduced to zinc in vapor form is withdrawn from the furnace through a second outlet passage and the molten brass is withdrawn from the furnace through a third outlet passage. The furnace is preferably an electric arc furnace although a gas fired furnace or an induction furnace may be employed.

摘要： A method of treating non-ferrous slag in a furnace by injecting liquid fuel and air into molten slag to heat and reduce the slag. The injection of the liquid fuel and air is obtained by discharging the liquid fuel under a pressure of at least 12 atmospheres through a nozzle to produce an atomized stream of the fuel, introducing the atomized stream of fuel into a stream of air, and carrying the mixed streams into the slag.

摘要： A novel pyrolysis process system for recycling of refuse wherein refuse is fed into a closed retort. The closed retort includes a moving molten lead bath for accomplishing the pyrolysis of the refuse. The pyrolysis process converts the organic portions of the refuse to a vapor state to facilitate ultimate recovery of tars, oils and other petroleum-related products, a part of which includes fuel that may be utilized to operate the system. The non-organic portions of the refuse are ultimately separated into high grade char, ferrous metals, non-ferrous metals and precious metals. The pyrolysis process exhausts no gases into the atmosphere and allows virtually all components of the refuse to be recycled into usable products.

摘要： Process and apparatus for salvaging bulky junk material of principally ferrous content characterized by crushing to predetermined thickness and thence shearing same into relatively small rectangular pieces, continuously conveying the pieces through a furnace to combust entrained combustible materials and separate, by melting, non-ferrous metals, resulting in a final ferrous product for subsequent refining which contains a minimum of contaminants to be removed in the refining process. Optionally, undesired combustible air pollutants formed in the furnace are also oxidized before discharge into the atmosphere to thus permit practice of the invention in loci where air pollution is not tolerated.

摘要： ALKALINE SOLUTIONS CONTAINING TELLURIUM AND SELENIUM BUT SUBSTANTIALLY FREE OF HEAVY METAL IONS, ARE TREATED WITH STRONG OXIDANTS TO PRECIPITATE HIGH PURITY ALKALI METAL ORTHOTELLURATE AT TEMPERATURES BELOW THE ATMOSPHERIC BOILING POINT. THE ORTHOTELLURATE MAY BE FURTHER TREATED BY CONTACTING IT WITH A REDUCTANT TO CONVERT TELLURIUM FROM THE +6 VALENCE STATE TO ITS +4 VALENCE STATE. THE PH IS THEN ADJUSTED TO THE ACID RANGE TO PRECIPITATE TELLURIUM DIOXIDE OF EXCEPTIONAL PURITY. HIGH PURITY METALLIC TELLURIUM MAY BE PRODUCED FROM THE TELLURIUM DIOXIDE IN ACCORDANCE WITH WELL-KNOWN TECHNIQUES.
