The energy required to liberate a mineral of economic interest from its gangue constituents in the host rock is described in this experiment. Numerous chances to get better energy and environmental presentation are linked with the mineral processing works. The design of equipment use for the purpose is indicated in some details. . It is now established information that the size reduction by grinding spent for more than half of the total cost. It is true in any mineral beneficiation plant; irrespective of the technique and methodology facilitate to achieve the improvement of the total separation of one or more valuable species in the natural ore. In the present experiment Manganese ore of hardness 6 on moha’s scale, specific gravity 3.53 has been taken for grinding tests in a ball mill. The experiments were conducted for three feed sizes (i.e. –1/2" + 3/8", –3/8" + ¼", –1/4" + 3/16") and three ball sizes (i.e. 1", 1/2", 3/4"). The values of selectivity function for giving pre impact to the feed using three set of feed sizes and three feed quantities (150, 100, 50 g) with three different ball sizes have been evaluated.
