the choice of crushers and grinders. The power or energy required is the sum of the work required to crush or grind the rock as well as to rotate the mill. The power required depends on the hardness of the rock, the initial size and the final product size required to achieve reasonable liberation of the mineral of interest, from the host rock. 3.3.
