Since it is common for the copper solvent extraction plant to supply feed electrolyte to an electrowinning plant, it is useful to combine the operating costs for the two plants when comparing costs of copper recovery by solvent extraction techniques with those for cementation. These have been summarized in the table which shows typical operating costs for a plant producing 30,000 annual tons ...

Copper sulfate solution is collected in the pregnant leach pond then pumped to the solvent extraction plant. The solvent extraction phase of treatment occurs in two stages. During the initial phase an organic solvent is used to recover copper ions contained in the pregnant leach solution, exchanging them with hydrogen ions in the acid. The final phase of the solvent extraction process employs ...
