2016-8-4 · Although the first large-scale application of copper recovery by solventextraction took place in Zambia in the early 1970s, it is only in the lastdecade that this technology has become widely employed in this part ofthe world and is now a mainstay unit operation in copper hydrometal-lurgical flow sheets. The mineralogy of the ores of the African Copperbelt,and hence the characteristics of African leach liquors, differs significantlyfrom those in Chile and the southwestern USA, where copper solventextraction has had a long and successful history. These differencesprovide operators, metallurgists, reagent vendors, and engineers withmany challenges: new approaches are needed to adapt solvent-extractiontechnology for successful implementation in this region. This paperexamines typical operating practice in the African Copperbelt,
