Gold Processing Stepscobalt Mining

gold processing - mining and concentrating | britannica,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..processing, smelting and refining gold | world gold council,the miller process is rapid and simple, but it produces gold of only about 99.5 percent purity. the wohlwill process increases purity to about 99.99 percent by electrolysis. in this process, a casting of impure gold is lowered into an electrolyte solution of hydrochloric acid and gold chloride..
