Leaching offers an alternative tocopper mining. 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 ofcopper sulphate. Thecopperis then recovered byelectrolysis. Thisprocessis known as SX-EW (solventextraction/electrowinning).

Some plants absorb metal compounds (including copper) when they grow . The plants can then be burned and the metal is extracted from the ash. The process is called phytomining and it can also be used to extract metals from contaminated land. Brassicas (the cabbage family) can extract metals including cadmium , cobalt and nickel.

The cyanide process is probably the best method yet devised for the chemical treatment of gold ores. In this process the ore is crushed and ground if necessary and the pulverized ore treated in wooden vats with a potassium or a sodium cyanide solution varying from one half to one per cent in strength.

Electrolysisis theprocessof using electric current to induce a chemical reaction. The chemical reaction in question is typically a reduction-oxidation reaction, wherein atoms exchange electrons and change oxidation states. Thisprocesscan be used to produce metal solids, which is useful for electroplating and the purification of various metals.
