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

Gold CIL CIP Gold Leaching Process Explained CCD

Nov 02, 2018  Cyanide is a lixiviant, or reagent that is used to leach, often in tanks, gold from a solid matrix and form a gold cyanide complex. The gold cyanide complex is then extracted from the pulp or slurry by adsorption onto activated carbon. CIL stands for carbon-in-leach.

Cyanide Use in Gold Mining - Earthworks

The cyanide dissolves the gold from the ore into the solution as it trickles through the heap. The pad collects the now metal-impregnated solution which is stripped of gold and resprayed on the heap until the ore is depleted. Vat (or tank) leaching: The ore is mixed with cyanide solution in large tanks.

Improving the process performance of gold cyanide

In the gold mining industry today, cyanide leaching is the prevailing method for solubilizing and recovering gold. Most of the new gold that is mined each year is processed via adsorption of gold cyanide onto activated carbon (Fleming et al. 2011). Typically, the carbon in pulp (CIP) or carbon in leach (CIL) process is used for gold recovery. These
