METHOD FOR PROCESSING GERMANIUM-CONTAINING MATERIAL Russian patent published in 1995 - IPC

FIELD: metallurgy. SUBSTANCE: used as carbon-containing material are coal and coal rocks such as aleurolite and/or argillite. Additionally introduced into charge are sulfur-containing additives and fluxes. In so doing, maintained in charge is the coal: coal rock: sum of sulfur-containing additives and fluxes ratio equalling (17-77):(20-68):(3-15). In this case, sulfur-containing additives are used in form of cakes of neutralization of gases of cyclone smelting, and/or electric melting of sublimates of cyclone smelting, and/or slags of electric melting of sublimates of cyclone smelting, and/or metal sulfides alloy of electric melting of sublimates of cyclone smelting wastes of germanium production. Fluxes are used in form of cakes of neutralization of gases of cyclone smelting and/or electric melting of sublimates of cyclone smelting, and/or slags of electric melting of sublimates of cyclone smelting, and/or salts of neutralization of gases of cyclone smelting presenting wastes of germanium production, and/or calcium carbonate. EFFECT: higher efficiency. 3 cl, 1 tbl
