copper heap leaching process

Heap Leach Process – Cyprium Metals Limited

Sulphide Heap Leach Process. The leached copper in solution is then processed by solvent extraction-electrowinning (SX-EW) to produce LME grade A cathode, which has a copper purity of more than 99.99%. All of the LME grade A copper cathode produced onsite is sold at a premium in liquid global markets whereas for concentrate, sales proceeds are ...
