03.07.2015There have been several methods developed by miners to extract gold particles from ore over the last hundred or so years. Of those methods, the 'Cyanide Leaching Process' (Cyanidation), is the method that is commonly used the most often to do this. As the name implies, the main component in the process is a sodium cyanide

A paper published by L. Elsner in 1846 first correctly identified the chemical reaction that forms the basis of all gold cyanide leaching processes: 4 Au + 8 NaCN + O 2 + 2 H 2 O → 4 Na [Au (CN) 2] + 4 NaOH The equation is well known, but the successful application of this reaction in a gold mining operation is rarely straightforward.

A very diluted form of sodium cyanide is used to dissolve and separate gold from its ore. This method was developed in Scotland in 1887 and was first used on a commercial scale by the New Zealand Crown Mines company in 1889. This method is supposed to be a much safer alternative to extraction with liquid mercury.

Process. Cyanide can be used to extract gold, either in a controlled mill environment, or more crudely on rock piles in the open. Cyanide vat leaching mixes finely crushed ore with a cyanide salt in water. The cyanide binds to the gold ions, and makes them soluble in water, thereby allowing separation from the rock.
