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.

recovering gold from sodium cyanide.? Gold Refining

Nov 07, 2016· However in the US (and likely the UK) Cyanide sets off alarms with environmental agencies and the Ferrocyanides do not, for that simple reason a distinction has value here. I know the metal finishing forums have discussed cyanide solutions for years. Refining, as does any stone process, requires some responsibility to be taken by the user.

Processing, smelting and refining gold World Gold Council

For extracting gold from low-grade ores, heap leaching is practiced; huge heaps are sprayed with a dilute solution of sodium cyanide, and this percolates down through the piled ore, dissolving the gold. There are very well defined rules for the safe and responsible use of cyanide as laid out in the International Cyanide Code. Gold refining
