Through this improvement, favorable results have been obtained with organic efficiency being well improved.

From setting up a mathematical model of the coal densimetric curve which features distribution function, the author studied the relationship between the mode and mean density of the curve and the organic efficiency of gravity separation.

0 Mt/a)of Linhuan Coal Preparation Plant;While treating raw coking coal of high refuse and ash content,good technical performance attained that qualified concentrate,pure middling and refuse be separated at low loss and high quantitative efficiency.

The paper describes a fully new method for assessment of coal washability, namely, special organic efficiency method, which is universally used to assess washability of raw coal washed with different cut-point.
