Advances in the Cyanidation of Gold ScienceDirect

Cyanidation, a process used for over a century to extract gold from free milling ores, is so effective that it can economically treat low-grade ores (0.5 g/t Au). The concentration of cyanide added to dissolve gold is much higher than the stoichiometric requirement because of various interferences.

Gold Mining Gold Production World Gold Council

2020-05-16· Gold mining is a global business with operations on every continent, except Antarctica, and gold is extracted from mines of widely varying types and scale. Mines and gold mining operations have become increasingly geographically diverse, far removed from the concentrated supply of four decades or so ago when the vast majority of the world’s gold came from South Africa.

Intensive Leaching Gekko

Cyanide leaching is commonly used worldwide for recovering gold from ore slurries or ore heaps. Gekko’s intensive cyanide leaching flowsheet advances the output of regular cyanide leaching. Combining higher concentrations of gold or silver with high cyanide and high oxygen amounts intensifies the stone leaching reaction to maximise mineral recoveries.
