Small scale copper elector-refinery Pyrometallurgy

2020-7-28  I would like to have experts’ suggestion about an application of SX in small scale copper elector-refinery (3-5 Kt/Y) and if it is tangible, are there any successful references. Main concept is to refine 97-98% grade copper Anodes to 99.999 pure Cathodes by using SX circuit to control impuriti

Copper Ore Hydrometallurgy and Pressure Leaching

Copper hydrometallurgy is a branch of metallurgy method to extract copper directly from those difficult-to-concentrate copper oxide ore. Traditional copper hydrometallurgy process typically consists of atmospheric leaching, solvent extraction (SX) and electro-winning (EW).

The copper in these products is mostly tough pitch copper, cathode copper into which 100–500 ppm oxygen has been dissolved during melting/casting. The remainder of unalloyed copper production is in the form of oxygen-free high conductivity copper with 5–10 ppm dissolved oxygen. These pure copper products account for about 70% of copper use.

Copper and nickel are extracted by the sulfuric acid-leaching route. Leached residue makes up the high-grade PGM–Cu concentrate containing 30–65% PGEs. The concentrate is further processed in steps of electrolytic refining (electrolysis), pyrometallurgy, and selective-solvent extraction refining for final separation of the pure precious metals.
