Processes

Leaching offers an alternative to copper mining First the ore is treated with dilute sulphuric acid This trickles slowly down through the ore over a period of months dissolving copper to form a weak solution of copper sulphate The copper is then recovered by electrolysis This process is known as SX-EW (solvent extraction/electrowinning)
