    In most gold ores the final process to extract the tiniest gold particles is the use of cyanide to dissolve the gold Cyanide in the presence of oxygen actually dissolves both gold and silver It is both efficient and inexpensive so it is widely used in precious metal ore processing.After milling sulfide ores may be subjected to chlorination bio oxidation roasting or autoclaving Chlorination is not commonly used to oxidize sulfide ores because of high equipment maintenance costs caused by the corrosive nature of the oxidizing agent Bio oxidation of sulfide ores employs bacteria to oxidize the sulfur bearing minerals.
