Abstract
Bureau of Mines research on the development of practical processes for recovering metals and other materials from various industrial wastes is described. The work had a dual purpose: pollution abatement and conservation of scarce, costly materials. Electrochemical machining sludges were filtered to recover the electrolyte and smelter to produce valuable nickel-base alloys. Salable alloys were also produced by smelting stainless steel mill wastes. Shredded paper was used to reduce the hexavalent chromium in chromium etching wastes, after which copper, zinc, and chromium oxide were recovered as separate products. Electric furnace steelmaking dusts were pelletized with a reducing agent and heated to reduce zinc oxide and volatilize 98 percent or more of the zinc as metal.
