Roasting temperature effect on the recovery of refractory gold and silver in pyrite concentrates

Roasting temperature effect on the recovery of refractory gold and silver in pyrite concentrates

Pyrite concentrates with refractory gold and silver were roasted at different temperatures to improve the recovery of the metals by cyanide leaching. Scanning Electron Microscope characterization of the calcine revealed that the gold occluded in the pyrite less than one micron, and roasting produced...
