Platinum-Group Metal

Nickel and cobalt are produced from laterite and sulphide ores. Cobalt is also produced from Central African copper–cobalt ores. Platinum-group metals, that is, Pt, Pd, Rh, Ir, Ru and Os, are predominantly extracted from sulfide ores from South Africa and Siberia. Their extraction always involves smelting followed by hydrometallurgical refining.
