beneficiation rare mineralogical coal

Coal Beneficiation - an overview ScienceDirect Topics

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.

Dry coal preparation without the use of water • STEINERT

Even today, traditional coal beneficiation is performed using coal washing with large amounts of water. It is then necessary to expend considerable energy drying the coal again. Moreover, in many regions of the world water is rare, and it is becoming more difficult for mines to obtain licenses for its use.
