Reduction of Fragment Size from Mining to Mineral Processing: A Review

The worldwide mining industry consumes a vast amount of energy in reduction fragment size from to mineral processing with an extremely low-energy efficiency, particularly ore crushing and grinding. Regarding such situation, this article describes the effects rock fragmentation by blasting on consumption, productivity, minerals’ recovery, operational costs whole chain processing, sustainability industry. main factors that influence are analysed as explosive, initiator, rock, distribution including blast design, models for predicting briefly introduced. In addition, two important issues—fines blending—are shortly presented. Furthermore, feasibility achieving optimum (satisfied minimum cost drilling-blasting crushing-grinding, maximum recovery ratio, high negative impact safety environment) is analysed. analysis indicates high. Finally, measures challenges discussed.
