gold is then leached from the carbon particles by a strong solution of sodium cyanide and sodium hydroxide, and it is recovered from solution by electrowinning directly onto steel wool or by the merrill-crowe process. In the latter process, the gold-bearing solution is deoxygenated and passed through a filter-press, where the gold is displaced from solution by reduction with zinc metal powder.
