Copper can be extracted from non-sulphide ores by a different process involving three separate stages: Reaction of the ore (over quite a long time and on a huge scale) with a dilute acid such as dilute sulphuric acid to produce a very dilute copper(II) sulphate solution. Concentration of the copper(II) sulphate solution by solvent 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.

Copper can be extracted from its ores by reduction. One of the common copper ores, malachite, which is composed of mainly copper carbonate, CuCO3xCu(OH)2, is heated to produce copper oxide with the release of carbon dioxide. CuCO3xCu(OH)2 → 2 CuO + CO2 + H2O The copper oxide is then heated with carbon to get copper. 2 CuO + C → 2 Cu + CO2
