ore flotation of oxidized copper

Copper Flotation Mineral Processing Metallurgy

A Copper Flotation Flowsheet Because the copper in this type of ore usually assays only plus or minus 1% copper, the porphyry copper operations must be relatively large in order to be commercial. The flowsheet in this study illustrates a typical 3,000 ton per day operation.

Ore deposits formed by oxidation and supergene enrichment

Ore Deposits Formed by Oxidation and Supergene Enrichment. An orebody thus becomes oxidized and generally leached of many of its valuable materials down to the groundwater table, or to depth where oxidation cannot take place. The effects oxidation may, however, extend far below the one of oxidation.

Ore deposits formed by oxidation and supergene enrichment

Sulfide minerals are oxidized at the surface and produce sulfuric acid, and acidified rainwater then carries the copper, as copper sulfate, down to the water table. Below the water table, where sulfide minerals remain unoxidized, any iron sulfide grains present will react with the copper sulfate solution, putting iron into solution and precipitating a copper mineral.

The effect of surface oxidation of copper sulfide minerals

The collectorless flotation of copper sulfide minerals is attributed to polysulfides on the surface as a result of mild surface oxidation (Lekki and Drzymala, 1990, Ekmeki and Demirel, 1997). Metal hydroxides on the mineral surface decrease the flotation of copper sulfide minerals even in the presence of collector (Senior and Trahar, 1991).
