METHOD OF PRODUCING HEAVY NONFERROUS METAL SULFIDE

摘要

FIELD: technology of inorganic chemistry. SUBSTANCE: precipitate obtained by precipitation with alkaline sulfur solution is treated additionally together with mother liquid with alkali, and then the parental metal salt solution is fed to suspension. For complete conversion of elemental sulfur alkali for treatment is taken at the ratio (1.25-0.75):1 to sulfur to be conversed, and 6-13 cycles of sulfidizing treatment were carried out. Method is used for producing nonferrous metal sulfides. EFFECT: improved method of metal sulfide producing. 3 tbl
