Beneficiation is the processing of ore to separate the target mineral from the waste rock. Before beneficiation, nearly all crude ore must be reduced in size. Primary crushing reduces ore from 2-4 feet boulders to rocks 8-10 inches in diameter. Secondary crushing reduces the ore into pieces less than 1 inch in diameter.
