Gold is processed by cyanide milling a chemical procedure that separates 95 to 98 percent of the gold from raw mined ore. It is then refined to the gold standard purity according to Mineweb. Heap leaching is a less expensive method of gold extraction but it is a longer process and it recovers less gold than the cyanide milling process. Chat Online
The Albion Process is an atmospheric leaching process used to oxidise refractory gold sulphide mineral concentrates. Such sulphide minerals are typical of the refractory gold mineralisation found worldwide and in particular throughout China, the Iberian Peninsula, and various regions in Latin America.

Some novel grinding devices such as high-energy ball mills (HEBMs) have been used as an alternative to the fine and ultra-fine ...
Leachox™ involves the oxidative treatment of refractory, sulphidic ores or concentrates with or without UFG (Ultra Fine Grinding) to liberate locked up or at least leach hindered gold. This may involve only particle surface cleaning immediately prior to the leach or actual oxidation of sulphide minerals.
REFRACTORY GOLD. By definition, refractory gold ores contain gold that is resistant to extraction by conventional chemical processing and as a result responds poorly to traditional gold cyanidation techniques such as Carbon-in-Leach (CIL), yielding less than 80% of the contained gold. Maelgwyn Minerals' Leachox Refractory Gold Process hits
The problems that result from refractory gold are caused by: Physical encapsulation of disseminated gold particles (usually less than a few micrometers in size) within a mineral that is unreactive and impervious to leaching ; Chemical interference by one or more of the ore constituents in the cyanide leaching process; Physical encapsulation

Gold processing - Gold processing - Mining and concentrating: The nature of the ore deposit determines the mining and mineral processing techniques applied. Oxide ore deposits are frequently of such low grade (e.g., 3 to 10 parts per million) that extensive mineral processing cannot economically be justified. In this case they are merely shattered by explosives and then piled into heaps for ...
