The goal of beneficiation is to eliminate inefficiency and waste by ensuring that as much recoverable material as possible is extracted from ore. A number of techniques can be used for this, often starting with grinding the ore into particles. Once ground, the particles can be sifted and sorted to extract usable material and set waste aside.

Jul 18, 2018 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).

Coal preparation, or beneficiation, is a series of operations that remove mineral matter (i.e., ash) from coal. Preparation relies on different mechanical operations, which will not be discussed in detail, to perform the separation, such as size reduction, size classification, cleaning, dewatering and drying, waste disposal, and pollution control.
