    The Problem with Coarse and Fine Coal BeneficiationThe Problem with Coal Recovery and Cleaning by FlotationCoal Flotation ProblemsCoal Beneficiation ProcessEconomic and operating conditions make it important to provide a simple, low cost, efficient method for recovering fine coal from washery waste. Not only is the water pollution problem a serious one, but refuse storage and disposal in many areas is becoming limited and more difficult. Many breakers and washeries efficiently handle the coarser sizes, but waste the coal fines. This problem is assuming major importance due to the increase in the amount of coal fines being produced by the mechani...
  • 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.
