Hence, theoretically, iron can be reduced to 5% without considering the iron dissemination in finer size ranges. In the size analysis, it was found that gangue minerals are concentrated in finer fractions and classification at 0.50 mm size can remove 44% alumina; 38% silica and 27% iron at 15% manganese loss. 3.

The separation effect was found to be better with the increase of feeding coal particle size, in particular, the coal particles with size larger than 5 mm underwent effective separation. The results reveal that the drag force of the fine coal separation process is an important factor restricting the separation efficiency.
