METHOD OF PROCESSING GOLD-CONTAINING ANTIMONIC CONCENTRATE

摘要

FIELD: metallurgy of non-ferrous and precious metals; production of antimony trioxide at accompanying separation of precious metals into self-contained commercial product. ^ SUBSTANCE: antimony sulfides from concentrate are dissolved by acid leaching-out with antimony pentachloride solution; one part of antimony trichloride solution is directed for extraction of antimony and other part is directed for making the leaching-out solution. Sulfur is removed from insoluble residue and gold head and gold-containing concentrate are separated by gravitation concentration method. ^ EFFECT: increased extraction of antimony and precious metals. ^ 15 cl, 3 tbl, 1 ex
