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 Properly done gravity concentration followed by flotation where necessary and then cyanide will recover
Get PriceGold electrolysis is the second good method used in gold making industries to separate gold from the other metals This procedure has been noted to produce gold that is almost % pure The principle and equipment for gold electrolysis Gold electrolysis was invented by Emil Wholwill in 1874 But various versions of this process have been
