Copper Mining and Processing: Processing of Copper Ores ...

This process uses a series of physical steps and high temperatures to extract and purify copper from copper sulfide ores, in four basic steps: 1) froth flotation, 2) thickening, 3) smelting, and 4) electrolysis.

Copper extraction - Wikipedia

Copper can be lost from the matte in three ways: as cuprous oxide (Cu 2 O) dissolved in the slag, as sulfide copper dissolved in the slag or as tiny droplets (or prills) of matte suspended in the slag. The amount of copper lost as oxide copper increases as the oxygen potential of the slag increases.

Fabrication and applications of copper sulfide (CuS ...

Copper sulfide is active spectroscopically (in UV–vis spectrum yields a peak at 620 nm) as well as electrochemically (during cyclic voltammetry provides couple of redox peaks between −0.4 V and −0.7 V at two different scan rates in an alkaline solution in a reversible electrochemical process) .

Treatment of Mixed Sulfide Oxide Ores of Copper

Beside the ores containing copper mainly as sulfide, with a small amount of oxidized copper, many of the large porphyry mines have oxide orebodies, in which the proportion of non-sulfide minerals is so high that present methods of treatment are inefficient.
