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.
