produce copper metal from chalcopyrite concentrates (Padilla et al., 2010; Habashi, 2007). However, copper production by heap leaching combined with SXEW has become a gigantic operation (Habashi, 2007). According to Watling (2006), more than 20% of refined copper is produced via hydrometallurgy.

In the case of copper, it is worth extracting when there is about 2 kg of copper per 1,000 kg of ore (%). Copper minerals are found in over one hundred varieties, although only a few have been worked for copper on a large scale. The most abundant ores are chalcopyrite and bornite, which contain both copper and iron sulphides.
