The Metallurgy of Cyanide Gold Leaching – An .

Nature of Gold: The surface of a gold particle will typically be dissolved at a rate of around 0.2-0.5 µm of surface depth per hour in a cyanide leach. For large gold particles and nuggets, this is too slow to be fully dissolved in a typical processing plant. Much simpler and less expensive gravity methods are available to recover this gold. Cyanidation is used for gold that is distributed ...

Cyanide-free gold recovery - CSIRO

The infrastructure for a processing plant that uses cyanidation typically costs $30 million, and is therefore, a barrier to entry for gold miners with smaller deposits that do not fit into the large-scale economies of gold production. Gold recovery by cyanidation is also of environmental and safety concern as it relies on the use of toxic cyanide.

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.
