To further evaluate the process of Gold Recovery by Gravity, Flotation and CarboninLeach Cyanidation, some cleaner tests with regrind of the bulk rougher concentrate, were conducted. Rougher flotation concentrates were reground to improve leach kinetics. The regrind sizes for these range of tests were not optimized. Regrind discharge sizes of between 24 to 64µm P80 were obtained.

Research on cyanidation methods brought considerable discussion on the reactions involved in the leaching and decomposition of pyrrhotite in cyanide solutions. Pyrrhotite has one loosely held sulphur atom which readily reacts with cyanide to form thiocyanate: Fe5S6 + NaCN = NaCNS + 5 FeS The ferrous sulphide oxidizes rapidly to the sulphate which reacts with cyanide to form ferrocyanide: .

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 is the most commonly used leaching process for gold .
Leaching gold with a cyanide solution remains the most widely used hydrometallurgical process for the extraction of gold from ores and concentrates. Despite the difficulties and hazards of working with cyanide, no other process has yet been proven to be an economic viable alternative.

This page primarily focuses on metallurgical mining, though many of the terms, processes, and concepts are the same within the nonmetallurgical extraction.
Sodium cyanide is an inorganic compound with the formula NaCN. It is a white, watersoluble solid. Cyanide has a high affinity for metals, which leads to the high toxicity of this salt. Its main application, in gold mining, also exploits its high reactivity toward metals. It is a strong base. When treated with acid, it forms the toxic gas hydrogen cyanide: Applications Cyanide mining Sodium ...
