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 reagents for mineral processing to recover gold, copper, zinc and silver represents ...
Cyanide Leaching | Mining | SGS
Cyanide leaching has been the industry standard for gold processing for more than 100 years. During the cyanide leach process, a cyanide solution, or lixiviant, is percolated through ore contained in vats, columns or heaps. Gold is dissolved by the cyanide and then removed from the heap or columns.

Cyanide Gold Extraction Process - JXSC Machine
Under the 400 mesh condition, the gold leaching rate increased by 8%. If the tower grinding machine is used to implement the edge grinding and immersion process in gold mines, it will be a major innovation in the cyanide gold extraction process. The cyanide gold extraction process also suits for copper leaching, zinc leaching, sliver leaching, etc.
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
