The energy required to liberate a mineral of economic interest from its gangue constituents in the host rock is described in this chapter. The design of equipment use for the purpose is indicated in some details. Standard laboratory tests for determining this energy are described for ball and rod mills systems of grinding.
The design of a ball mill can vary significantly depending on the size, the equipment used to load the starting material (feeders), and the system for discharging the output product. The size of a mill is usually characterized by the ratio "length to diameter" and this ratio most frequently varies from 0.5 to 3.5. The
Rod, Ball and Pebble Mills. The products from AG or SAG mills typically feed secondary grinding mills with particles that range in size from 5 cm down to below 100 microns (0.1 mm). The final particle size is determined by downstream processing requirements. Grinding is carried out as a wet process with water content between 50 – 70% by weight.

By adjusting flotation process parameters, the mineral processing efficiency and mineral resource recovery rate can be significantly improved. Optimizing the chemical system, flotation machine parameters, flotation machine selection and flotation process can effectively improve the overall effect of copper ore flotation.
A ball mill is a kind of grinder that grinds and blends materials for the purpose of mineral processing, paint production, pyrotechnics, ceramics, and selective laser sintering. It works on the principle of impact and attrition: the balls are released from the top of the shell and then crush and grind the material to fine powders.
A copper ore including 1.2 Cu %, 1.02 % Pb and 0.26 % Zn was subjected to experiments. Copper mineral in the ore is chalcopyrite and dominant gangue minerals are pyrite and quartz. Ore sample in size of approximately -14 mm was taken from the ball mill feed of the plant and was crushed down to 3.36 mm
