  • 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 (not discussed in detail here) to perform the separation, such as size reduction, size classification, cleaning, dewatering and drying, waste disposal, and pollution control.

    Coal Beneficiation Technology 2007 Initiatives, Policies

    Coal Beneficiation Coal beneficiation is a process by which the quality of raw coal is improved by either reducing the extraneous matter that gets extracted along with the mined coal or reducing the associated ash or both. Two basic processes of beneficiation: Dry-deshaling: Non-coal or shaly-coal is removed without using any liquid media.
