TENORM: Copper Mining and Production Wastes | US EPA

Once PLS is leached, it is sent to a solvent extraction plant to remove the copper. The PLS is mixed with an organic solvent that binds to the copper and chemically separates the copper from the rest of the liquid. Then, the copper-bearing liquid is combined with another acid to precipitate the copper from the organic material.

Copper Purification by Spencer Reichert on Prezi

Copper purification is the removal of impurities in copper, this making it pure. Extracted from copper ore by reduction with carbon, however, this copper is impure, and so it must be purified One impure copper bar (anode) and one pure copper bar (cathode) placed in electrolytic cell using CuSO4 solution.
