copper smelting process flowchart

Electrowon copper cathodes are as pure as or purer than electrorefined cathodes from the smelting process. Thus they are well received by the market. Whereas the conventional process requires an estimated 65 MJ/kg of energy (not including scrap recycling ) the SX/EW process requires an estimated 15 MJ/kg (from heap or dump leaching) to 36 MJ/kg.
