    Gold cyanidation

    Gold cyanidation (also known as the cyanide process or the MacArthur Forrest process) is a hydrometallurgical technique for extracting gold from low grade ore by converting the gold to a water soluble coordination complex. It is the most commonly used leaching process for gold extraction.

    Gold and Silver Leaching by Cyanidation

    What is the Effect of Aeration on Gold and Silver Leaching. Another of the prime requisites of successful cyanidation is free oxygen. Pure oxygen is too expensive to use, instead atmospheric air is the customary source of the required oxygen gas. Some interesting experiments have been conducted using Ozone but the practice has not been adopted commercially on account of the cost in the gold

    144 CYANIDATION OF GOLD ORES which is a reduction step, H202 + 2e ~ 20H , takes place only to a minor extent. In fact, the dissolution of gold is inhibited if large amounts of H202 are present due to the oxidation of cyanide ion to cyanate ion. Cyanate ion has no dissolving action on the metal CN + H20 2 ~ CNO + H20 4.
