process gold recovery from ore using cynide

In some special circumstances, some of the other methods may show promise, but for a good oxide gold ore, CN leaching is usually the best of the leach methods for the yellow precious metal. Silver is also leached easily using cyanide, however much silver ore is in sulfide forms, and at higher concentrations (several ounces per ton and above ...

Dissolve Gold and Silver with Cyanide

The addition of gold or silver to an alkaline sodium cyanide solution will cause the gold and silver to react with the cyanide and dissolve into the solution in a process called cyanidation. This process is more frequently referred to as leaching. As well as reacting with the precious metals, the cyanide will react with iron, copper or zinc that may be in the ore.
