CYANIDE HEAP LEACHING

Heap Leaching: extraction of gold using heap leaching and carbon recovery Cyanide has a natural affinity for gold, which dissolves in it just as sugar would in a hot drink. Cyanidation has been the principal method of extracting gold from ore since the development of the MacArthur-Forrest Process in 1887, which proved crucial in the development of the South African gold mining industry.

Heap leaching

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.[1] Production of reagents for mineral processing to Get price
