Leaching dissolves the gold out of the ore using a chemical solvent The most common solvent is cyanide which must be combined with oxygen in a process known as carboninpulp As the cyanide and oxygen react chemically gold in the pulp dissolves When workers introduce small carbon grains to the tank the gold adheres to the carbonGet Price
The Miller process uses gaseous chlorine to extract impurities when gold is at melting point impurities separate into a layer on the surface of the molten purified gold The Miller process is rapid and simple but it produces gold of only about 995 percent purity The Wohlwill process increases purity to about 9999 percent by electrolysisGet Price
