The first step in the mining and processing of nearly any mineral ore is comminution. Since the oil embargo of 1979, the mining companies have been striving to reduce energy consumption and costs. The first serious step was the introduction of in-pit crushing in the early 1980s. With in-pit crushing accepted as a standard design mode, the energy saving emphasis turned to …
