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 (tailings). Examples of beneficiation processes include froth flotation and gravity separation. Other economic uses of the term are in use. For example, in the diamond industry, the beneficia…
Coal beneficiation: Policy priorities for India | ORF
Coal beneficiation is a physical process that separates burnable coal from associated un-burnable mineral matter, also known as ash, or rejects. High ash content is inherent in Indian coals, the ash having been deposited concurrently with the coal …

process of Coal Washing. Considering the fact of requirement of millions of tones clean coal for the end-users, mainly power houses, this problem will have to be solved effectively. The benefits of low ash coal burning in boilers are realized but reimbursement of extra cost of beneficiation for washed non-coking coal needs to be considered
US4412842A - Coal beneficiation process - Google Patents
Coal is beneficiated by slurrying coal particles of less than 200 microns in diameter with water. The slurry is cavitated with intense sonic agitation at a level of at least 15 joules/cm 2 . While the slurry is in the cavitated state, impurities and water are gravitationally separated from the slurry to produce a coal/water mixture having up to 40 percent by weight water, and preferably, 20 to ...
