The first step of Beneficiation is to crush or grind the coal to liberate the coaly matter from ashy matter which can theoretically yield complete liberation In the case of intergrown texture finer grinding up to a few micron size is necessary for complete liberation whereas for free dirt ordinary crushing is sufficient Kumar D 1982
