Mineral Processing
The slag in the converter for copper matte converting has copper content 4–6%. Mineral processing will render the copper concentrate with copper content 24–28%, and copper recovery is 90%. The copper concentrate obtained from mineral processing of smelting slag will be returned to smelting furnace for further smelting.

Advances in depressants for flotation separation of Cu-Fe …
The flotation separation of Cu-Fe sulfide minerals at low alkalinity can be achieved using selective depressants. In the flotation system of Cu-Fe sulfide minerals, depressants usually preferentially interact with the pyrite surface to render the mineral surface hydrophilic and hinder the adsorption of the collector. This review summarizes …
