gold ore gravity concentration process increase quality

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.

The Metallurgy of Cyanide Gold Leaching

With lower gold grades beneficiation (usually flotation) is often used ahead of leaching to increase the grade of Au and reduce the quantity of ore to be leached. Nature of Gold: The surface of a gold particle will typically be dissolved at a rate of around 0.2-0.5 m of surface depth per hour in a cyanide leach.

Gold Ore Processing

The concentration of gold in the Earth's crust and mantle is extremely low and highly variable, resulting in ore variability in many gold and copper–gold deposits. More importantly, gold in an ore may occur in two or three forms (i.e., microscopic gold, submicroscopic gold, and surface gold), making gold ore processing extremely challenging.
