The process of extracting gold from ore with cyanide is called cyanidation. The reaction, known as Elsner's Equation, is: 4 Au + 8 CN+ O 2 + 2 H 2 O = 4 Au(CN) 2+ 4 OHAlthough the affinity of cyanide for gold is such that it is extracted preferentially, cyanide will also form complexes with other metals from the ore, including copper, iron ...

How to recover gold from cyanide solution. Recovering gold from cyanide solution is a very old method, and, it is still employed in large scale recovery of gold from its ores. Oxygen also plays an important role in the leaching of gold in a cyanide solution. This fact is very much utilized in the gold extraction in private and government ...
Leaching dissolves the gold out of the ore using a chemical solvent. The most common solvent is cyanide, which must be combined with oxygen in a process known as carboninpulp. As the cyanide and oxygen react chemically, gold in the pulp dissolves. When workers introduce small carbon grains to the tank, the gold adheres to the carbon.

Yes there are a couple of other processes for extracting gold from ore, but they are more dangerous than cyanide. Cyanide is actually fairly easy to manage, and although it CAN kill you, exposure to cyanide can be treated (they should work fast!) and recovery is complete (basically, if it doesn't kill you right away, you will probably completely recover with no ill effects).
