Pretreatment Of Refractory Gold Ore With Microwaves

Microwave pretreatment of a double refractory gold ore

For both conventional and indirect microwave roasting, gold recoveries of over about 98% were achieved after cyanide leaching. For microwave roasting, both the total carbon removal rates and the heating rates were higher and the specific energy consumptions were lower than the corresponding values for conventional roasting.

Microwave pretreatment of a double refractory gold

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 method and the results were compared to those obtained by conventional roasting. The compositional changes of the ore during roasting were determined by thermogravimetric analysis (TGA). Also, both the real and

Pretreatment of refractory gold-bearing sulfur

After roasting refractory gold-bearing sulfur concentrates by microwave, the influences of microwave power, the ore mass and roasting time on sample mass loss rate and leaching rate were investigated. The results show that sample mass loosing rate is 28.12% and iodide leaching rate is 71.56% after 900 g raw ore is roasted for 50 min at power of 16 k W, and the leaching rate after microwave
