METHOD FOR TREATMENT OF ZINC SULFIDE OR OTHER ZINC-CONTAINING MATERIALS, METHOD FOR PARTIAL OXIDATION OF MATERIALS CONTAINING ZINC OXIDE, ZINC SULFIDE AND IRON SULFIDE, METHOD FOR TREATMENT OF INITIAL MATERIAL CONTAINING ZINC SULFIDE AND IRON SULFIDE Russian patent published in 1998 - IPC

FIELD: nonferrous metallurgy; methods for treatment of materials containing zinc. SUBSTANCE: method for treatment of zinc sulfide or some other zinc-containing materials together with mineral containing iron sulfide provides for treatment of initial raw materials at temperature of 1250-1400 C and oxygen partial pressure within $$$ bar with obtaining bath of melt of matte homogeneously mixed in bath with slag phase, from which formed vapors of zinc, sulfur, sulfur oxides and zinc sulfides are removed and transported with the help of carrier gas introduced into bath. In this case part of FeO is generated from iron sulfide. Offered also are method of partial oxidation of materials containing zinc oxide, zinc sulfide and iron sulfide, and method for treatment of initial material containing zinc sulfide and iron sulfide. EFFECT: production of high-quality products with lower expenditures and for shorter periods of process time. 20 cl, 3 dwg, 1 tbl
