  • 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 classifiion, cleaning, dewatering and drying, waste disposal, and pollution control.

  • Beneficiation Wikipedia

    In the mining industry or extractive metallurgy, beneficiation is any process that improves (benefits) the economic value of the ore by removing the gangue minerals, which results in a higher grade product (concentrate) and a waste stream ().Examples of beneficiation processes include froth flotation and gravity separation.. Other economic uses of the term are in use.
