By far the greatest proportion of copper is extracted from the sulfides of copper, iron and sometimes other metals. Such ores originate from sulfur-bearing volcanic magmas, which have separated into metal sulfides and siliceous melts.Extraction of copper from copper pyrite $left(mat{CuFeS}_{2}right)$ involves (A) crushing followed by concentration of the ore by froth-flotation (B) removal of iron as slag (C) self-reduction step to produce 'blister copper' following evolution of $mat{SO}_{2}$ (D) refining of 'blister copper' by carbon reduction.
