METHOD OF COMPREHENSIVE REPROCESSING OF PYRITE CALCINES Russian patent published in 1994 - IPC

Abstract RU 2025518 C1

FIELD: metallurgy and chemical technology. SUBSTANCE: pyrite calcine from calcination of iron pyrites is leached by hydrocarbon acid solutions. Crude copper is precipitated by cementation after adding iron scrap. Alkaline agent is dosed up to reaching 5.0 pH value. Aluminium hydroxide is precipitated, and then the solution is directed to precipitate iron and zinc containing products. EFFECT: comprehensive reprocessing of pyrite calcines. 1 tbl
