Microwave pretreatment of a double refractory gold ore,

01/09/2007· With regards to the application of microwaves to refractory gold ores, Haque, 1987a, Haque, 1987b has studied the microwave pretreatment of refractory sulphidic ores and achieved gold extractions of over 98%. However, there is no information published on the microwave processing of the double refractory gold ores. In this paper, microwave pretreatment of a double refractory gold oreMicrowave 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.Microwave pretreatment of a double refractory gold ore,,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,
