refractory ore gold and pretreatment 212

Abstract 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
