US4412842A Coal beneficiation process Google Patents

In accordance with the present invention, a process for the beneficiation of coal is provided which washes the coal during slurrying, impregnates the coal and concentrates the slurry to a high coal content. Coal is beneficiated by slurrying coal particles of less than 200 microns in diameter with water.
