Reduction of Fragment Size from Mining to Mineral Processing: A
2022年10月4日· 21 Energy Rock drilling, blasting, and comminution (crushing and grinding) consume a vast amount of energy in hard rock mines As mentioned in Sect 1, statistics from hard rock mines indicates that drilling and blasting consumes 2% and comminution does 53% of the total energy input in the whole production chain frommining operations For example, in 2000 the amount of crushed rock produced was 17 billion tons With an average ore recovery ratio of 94 percent, the amount of waste material produced was 130 million tons This calculates to a total of 18 billion tons of materials handled in crushed rock mining Figure 92 Materials Handled for Crushed RockLimestone and Crushed Rock Department of Energy
