  5. solvent stripping of copper ore

solvent stripping of copper ore

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

As a leading global manufacturer of crushing equipment, milling equipment,dressing equipment,drying equipment and briquette equipment etc. we offer advanced, rational solutions for any size-reduction requirements, including quarry, aggregate, grinding production and complete plant plan. If you are interested in these product, please contact us.
