Microwave pretreatment of a double refractory gold ore ... Double refractory gold ores, such as Barrick's 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.

Microwave pretreatment of a double refractory . Abstract. Double refractory gold ores, such as Barricks Goldstrike ore, contain both pyrite and carbonaceous matter and .
The treatment process of a lowgrade refractory gold ore containing sulfide minerals and carbonaceous matters was studied in this work. The gold extraction of this ore by allsliming cyanidation was only %. Hence, a pretreatment was necessary. In this paper, a flotationpreoxidationcyanide leaching process was developed.
The gold ore must be pretreated to oxidize sulfide minerals associated with gold and to remove other minerals and chemical compounds that interfere in the cyanidation leaching process. The recovery of gold from refractory sulfidiccarbonaceous ores after roasting pretreatment was studied.
