Alternatively, the matte produced by the pyrometallurgical route is further refined by conventional hydrometallurgical pressure oxidation and electrolysis/selective solvent-extraction techniqu Copper is removed by adding hydrogen sulfide, leaving a metal concentrate of only nickel and cobalt.

Pyrometallurgy of copper 4 Conversion • After smelting, matte contains from between 30 to 80% Cu in the form of copper sulphide • The sulphur is removed by selective oxidation of the matte with O 2 to produce SO 2 from S, but leave Cu metal • Converting is carried out in two stages: 1) an iron removal stage, and 2) a copper-making stage.
