Gold Ore - Home Facebook

The primary consumers of cyanide in a typical gold plant are soluble iron and sulphide. Preoxidation with a MACH REACTOR™ oxidises ferrous to ferric and precipitates ferric hydroxide and oxyhydroxides. A ferric hydroxide layer is also formed on the surface of the mineral to prevent further leaching of deleterious cyanide consumers.
