Copper extraction refers to the methods used to obtain copper from its ores.The conversion of copper consists of a series of physical and electrochemical processes. Methods have evolved and vary with country depending on the ore source, local environmental regulations, and other factors.. As in all mining operations, the ore must usually be beneficiated (concentrated).

The use of a sulfuric acid pretreatment on a gold and coppercontaining oxide led to a decrease in cyanidesoluble copper from 12.12% to 0.25%, which caused a reduction in NaCN consumption from 2011 g/t to 785 g/t. Concurrently, gold extraction increased slightly from 97.30% to 99.80% (Clareti Pereira and da Silva Borges Barbosa, 2017).
