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 joulescm 2 . While the slurry is in the cavitated state, impurities and water are gravitationally separated from the slurry to produce a coalwater mixture having up to 40 percent by weight water, and preferably, 20 to ...

Coal Beneficiation Technology 2007 Initiatives

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.
