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 ...
