Grinding is usually dividen into two stages. Due to a granularity of useful minerals to monomer is very small, something needs to be ore ground to a fineness of less than 0.074 mm of, even in detail, to make some kind of useful minerals to achieve isolation. As far as breaking in large plant generally use the coarse, medium and fine three-stage crushing (there are four), the ore block size gradually shrink to about 8~25 millimeters, and then sent to the mill for grinding. Till useful mineral particles can achieve isolation.
