Innovations: Introduction to Copper: Mining & Extraction
The barren rock, or gangue has to be separated from the sulfide minerals in order to smelt the metallic copper from the ore. 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: Copper glance (Cu 2 S) is roasted in the presence of air. This results in oxidation of copper sulphide to give copper oxide. Roasting turns copper glance (ore of copper) into copper (I) oxide. 2Cu2S + 3O2 ⇨ 2Cu2O + 2SO2 After that, copper oxide is then heated in the absence of air, so that it can undergo calcination.
