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.
These issues can by and large be addressed by resorting to Coal beneficiation. Need for using beneficiated coal further assumes importance for compliance to environmental requirement which stipulates that power houses situated beyond 1000 Kms from pithead coal mine must use coal having less than 34% ash.
