METHOD OF PROCESSING OXIDIZED COPPER ORES Russian patent published in 2000 - IPC

Abstract RU 2149709 C1

FIELD: mineral concentration. SUBSTANCE: method includes preliminary sulfidizing of copper minerals by sulfoagglomeration and subsequent flotation. Sulfoagglomeration charge is composed of oxidized copper ore, sulfur-containing material and coke. Produced agglomerate is crushed, ground and floated with separation of copper concentrate, pyrite concentrate and tailings. Sulfur-containing material may be used in the form of pyrite-containing tailings of concentration mills, substandard ore, flotation pyrite concentrate, etc. EFFECT: higher recovery of copper and precious metals. 6 cl, 1 ex
