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

Integrated process for coal chemical demineralization and spent caustic
Conventional coal washing plants generate clean coal with 15–18% ash content and 35–50% yield by several physical beneficiation techniques. Handling and disposal of the rest of 50% reject is an environmental concern and hence, alternate processes for utilization of high-ash washery rejects are of high importance. ... (eh-pH …
