    Leaching offers an alternative tocoppermining. First, the ore is treated with dilute sulphuric acid. This trickles slowly down through the ore, over a period of months, dissolvingcopperto form a weak solution ofcoppersulphate. Thecopperis then recovered by electrolysis. Thisprocessis known as SX-EW (solventextraction/electrowinning).
