Chalcopyrite (Cu) Sphalerite (Zn) Separation by Flotation
Copper 3.78%; Sulphur 42.38%; Zinc 12.45%; Gold 0.01 oz/ton; Iron 32.84%; Silver 1.50 oz/ton; Insoluble 8.50%; In order to meet smelter requirements it is desired to produce at least a 20% copper concentrate with not over 8% zinc. The copper is present principally as chalcopyrite in extremely close association with both the sphalerite and pyrite.

Flotation and Tailing Discarding of Copper Cobalt Sulfide Ores
The mineral composition of copper–cobalt ores is more complex than that of copper sulfides, and it is also difficult to discard tailing efficiently in primary flotation for the fine-grained disseminated of ore. In this work, a mineral liberation analyzer (MLA) was employed to study the characteristics of minerals. As a significant mineralogical characteristic, the liberation …
