In the case of gold, after adsorbing onto carbon, it is put into a sodium hydroxide and cyanide solution. In the solution the gold is pulled of the carbon and into the solution. The gold ions are removed from solution at steel wool cathodes from electrowinning. The gold then goes of to be smelted[11].
