Mining Industry Energy Bandwidth Study
The mining process is unique in that unlike most industrial processes, the starting raw materials and conditions for production vary widely, sometimes by more than an order of magnitude, in energy intensity (Btu/ton produced). Therefore, an average theoretical value was approximated by evaluating the average performance efficiency of mining equipment.
