reaction of gold with sodium cyanide

reaction of gold with sodium cyanide

+

The ore is ground and crushed and any free gold is extracted by use of gravity as it may be too large to react readily with the cyanide. If the gold ore contains other metals and/or sulphide minerals it may require additional treatments prior to the leaching process. The treated gold then has sodium cyanide added to it and the following
