Kanowna Belle is a refractory gold operation located near Kalgoorlie in Western Australia. The primary ore to be treated is refractory in nature, exhibiting only 7075% recovery, even after fine grinding and cyanidation. The ore has a low average sulfide content of approximately 1%, predominantly pyrite.

The Leachox refractory gold process has to date been applied to the selective. For refractory sulphide ore bodies Imhoflot pneumatic flotation would In theory grinding ores to gold particle liberation size should then render them amenable to. Recovery of Gold in Pyritic Sulfide Ores Mine Engineer

Improving the gold leaching process of refractory ores

Improving the gold leaching process of refractory ores

To improve the leaching kinetics of refractory ores and gold recovery, a number of pretreatment techniques are employed prior to cyanidation. These include roasting, biological and pressure oxidation and Albion and Leachox processes. Roasting is the first process employed to increase the leachability of refractory gold ores.

hangingwall graphitic phyllite. Gold mineralization is associated with a complex array of deformed quartz veins and arsenopyrite disseminations in the silicasericitecarbonate altered metasediments and granitoid. The fresh or sulphide mineralization is refractory but it is not included in mineral reserves or production schedules.

The common definition of quot;refractoryquot; gold ores, are those ores that do not allow the recovery of gold by standard gravity concentration or direct cyanide leaching. One major category of refractory ores are gold values contained within the crystalline structure of sulfide minerals such as pyrite and arsenopyrite.
