Abstract:Research progress on mechanical activation assisted leaching of gold-bearing sulfide ores in recent decade is summarized. Mechanism of mechanical activation, mechanical activation enhanced leaching process of sulfide ores and application of mechanical activation equipments are discussed. Modern analysis methods and quantum theoretical models are recommended to be applied in study of mineral interface change before and after mechanical activation, and mechanical activation mechanism should be established based on special equipment and leaching process. Finally, the prospect and trends of mechanical activation development are proposed.
