PRESSURE LEACHING RPMGlobal

This plant was a medium temperature process where sulfides were oxidized at 150o C and approximately 1,400 kPa using oxygen. Its success resulted in the construction of an additional plant at the Flin Flon mine (1993). A major revolution in gold processing was the pressure oxidation of refractory, pyritic ores.

Gold extraction

A quot;refractoryquot; gold ore is an ore that has ultra fine gold particles disseminated throughout its gold occluded minerals. These ores are naturally resistant to recovery by standard cyanidation and carbon adsorption processes. These refractory ores require pre treatment in order for cyanidation to be effective in recovery of the gold. A refractory ore generally contains sulfide minerals, organic carbon,

Microwave pretreatment of a double refractory gold ore

Double refractory gold ores, such as Barricks Goldstrike ore, contain both pyrite and carbonaceous matter and the latter results in the loss of gold from solution during cyanide leaching. One possible remedy is to roast the ore and thus oxidize the pyrite and remove the organic carbon.
