equation for copper extraction from its sulphide ore

Copper is extracted from copper pyrites by

Solution: The formula of copper pyrites is C u F e S 2. In auto reduction, the sulphide ores of the metals which are less electropositive like H g, P b and C u are heated in the air so as to convert a part of it to its oxides. These oxides then react with the remaining sulphide ore in the absence of air, to give the metal and sulphur dioxide.

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.
