Pyrometallurgy an overview ScienceDirect Topics

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.
