The separation of cobaltite from chalcopyrite and

1976-5-1  The intimate association and complexity of the minerals make flotation the logical method of beneficiation [ 1 ]. In this paper, the separa- tion of cobaltite (CoAsS) from other sulphides, namely, chalcopyrite (CuFeSa) and pyrite (FeSz) is described. Experimental techniques Natural crystals of cobaltite, chalcopyrite and pyrite were used.

Copper-Cobalt ores

Cobalt is floated using a combination of xanthate and dithiophosphate and/or MBT. Depending on the cobalt mineralization, use of an activator such as copper sulphate. could provide improved metallurgy when floating with a combination of xanthate and dithiophosphate at a pH 8-9.

Separation of cobaltite - CALIFORNIA RESEARCH CORP

I have found that cobaltite can be readily and efficiently separated irom pyrite or pyrrhotite; or from both if present together, by subjecting the mineral mixture to treatment with lime, and thereafter subjecting the mixture to flotation in a system of pH not greater than about 7 in the presence of a xanthate collector and a depressant for the cobaltite, and floating the pyrite and/or pyrrhotite away from the cobaltite in this system of controlled pH with the aid of the said flotation

Cobaltite - an overview ScienceDirect Topics

Cobaltite is a strategically significant mineral (Fig. 1.17) composed of cobalt, arsenic, and sulfur (CoAsS) crystallizing in the orthorhombic (or pseudocubic) system resembling pyrite.It contains up to 10% iron and a valuable amount of nickel. The name is derived from the German “Kobold” meaning “underground spirit” or “goblin” in allusion to the refusal of cobaltiferous ore to ...

flotation of cobalt ore

2020-11-19  Sep 01, 2020 A specific cobalt flotation circuit is run at KCM’s Nchanga concentrator. The ore from the Nchanga open pit contains pockets of ore with higher grades of cobalt, typically about 0.3% cobalt and 1.3% copper. This ore is processed in campaigns through the cobalt flotation circuit, which is illustrated schematically in Fig. 11.
