Thermal Beneficiation of Sulfide Ore Materials

Including sulfide ore beneficiation tailings in sulfide ore processing is mainly ascribed to their use in the construction industry. In addition to dump products, various other wastes are formed during processing of sulfide ore materials, and these wastes are sent into circulation for pyrometallurgical processing. This study proposes a device for thermal beneficiation of gold-containing sulfide ore materials using a tubular purge grate. Gas purging through the holes of hollow rings, which are arranged in a staggered order, will evenly distribute bubbles throughout the volume of the slag melt and also evenly mix it. Gas purging of only the molten slag will reduce energy consumption.
