The Current Status of Cyanide Regulations  E  MJ
The Current Status of Cyanide Regulations E MJ

Cyanide is a naturallypound that bonds with gold, allowing it to be brought into solution. It can easily be separated from gold for collection. It is a simple, cost effective process. No suitable alternatives exist. In other words, banning the use of cyanide in effect bans the extraction and production of gold.
