Mineral comminution: Energy efficiency

2008-7-1 · Estimations of energy consumption by DOE (2005) during mining operations show that 39% is used for beneficiation and processing operations of which 75% is accounted for by comminution, indicating that comminution consumes approximately ∼29.3% of the total mining energy in the USA. This number is likely to be generally applicable to mining world wide and useful for assessing the fraction
