METHOD OF PROCESSING OF COPPER CONCENTRATES Russian patent published in 1999 - IPC

Abstract RU 2139947 C1

FIELD: preparation of concentrates for pyrometallurgical conversion. SUBSTANCE: method includes sintering of charge on sintering plant. Introduced into charge, in addition to copper concentrate, is complex flux in amount of 20-60% to ensure ratio of (FeO+CaO)/SiO₂=1-4. Complex flus is offered in form of mixture of limestone and quartzite wastes of concentration of ores (of corresponding chemical composition), and slag of ferrous metallurgy (of blast-furnace and steel-melting processes). EFFECT: high productivity and improved physico-chemical properties of sinter. 3 cl, 2 tbl
