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 sulfurbearing volcanic magmas, which have separated into metal sulfides and siliceous melts.

Copper Article about copper by The Free Dictionary

Because of the high affinity of copper for sulfur and of the components of the gangue and of iron for oxygen, copper is concentrated in molten sulfides (matte), while the oxides form the slag. On standing, the matte separates from the slag. In most modern plants the smelting operation is carried out in reverberatory or electric furnaces.
