10.5.1.5 Copper extraction using emulsion liquid membranes. Solvent extraction has been routinely used for copper refining since its invention in the 1960s, and it is suggested that well over 10% of refined copper production from ores is obtained by solvent extraction, accounting for millions of tonnes of metal.

About 80% of all copper extracted comes from sulphide ores. A typical ore contains only 0.5% to 2.0% copper. It is a measure of the value of copper that it is worth extracting it from such small concentrations. The ore is a mixture of minerals and rock (called gangue). The most common copper minerals are:
