leaching copper concentrate - MC World

The electro-refining of copper is a multi-step process that starts with copper concentrate that is smelted to produce impure copper anodes, which are then electrorefined to produce LME Grade A copper cathode (+99.99%). A simplified block flow diagram of copper refining is shown below. A key aspect of copper electrorefining is the control of copper concentration and impurities in the ...

Applications of Copper Electrowinning - emew Blog

The emewPlate cell is used for more concentrated electrolytes generally when the target metal concentration is greater than 10 g/L. The emewPlate cell is often used for recovering copper, nickel and tin cathode in a variety of applications including mining, refining, and recycling. The emewPlate cells can also be paired with solvent extraction (SX) and ion exchange (IX) when pre-concentration ...
