Microwave pretreatment of a double refractory
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. In this research, microwave roasting of a double refractory gold ore was investigated as an alternative refractory gold ore extraction by using vaccuum ovenrefractory gold ore extraction by using vaccuum oven .
