  • Microwave heating of gold ores for enhanced grindability

    Microwave processing enhanced the grindability of the ore, and crushing strength was reduced by 31.2%. The presence of microcracks improved leaching rate, and over 95% extraction was achieved within 12 h as against 22 h for the nonmicrowaved sample. Such a strategy can be used to maximize recovery and manhours on processing plants.
