Process Of Cyanide Leaching Of Gold

Gold cyanidation - Wikipedia

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. Production of reagentsfor mineral processing to recover gold, copper, zinc and silver represents approximately 13% of cyanide consumption globally, with the remaining 87% of cyanide used in other i…

Cyanide Leaching Chemistry & Gold Cyanidation

The reactions that take place during the dissolution of gold in cyanide solutions under normal conditions have been fairly definitely established. Most agree that the overall cyanide equation for leaching and cyanidation of gold is as follows: 4 Au + 8 NaCN + O2 + 2 H20 = 4 NaAu(CN)2 + 4 NaOH

The gold is mixed with the sodium cyanide which leads to the following Elsener’s equation and reaction. This is done to make soluble gold; Now the gold is soluble. This method of making soluble gold is known as leaching. In the process of leaching, a dilute form of sodium cyanide is added into the ore containing the gold.
