Solvent extraction electrowinning is a complex process of chemical reactions, but can be simplified into three main steps: Heap Leaching Copper Ore with Agglomeration. Crushed copper ore is first typically processed via heap leaching. An effective leaching step is critical to SX-EW, as it sets the stage for how much copper can be recovered.
Electrowinning Copper. In the electrowinning stage of copper extraction, the solution containing the copper ions is pumped through a series of tanks. Suspended in these tanks are sheets of lead alloy (anodes) alternating with cathodes made of either thin copper starter sheets or stainless steel blanks.
