Abstract

The processing of two samples of high ash Indian coking coal fines (-500m) has been studied. Mechanical cell flotation of two coal samples resulted in poor recovery of combustibles at a specified ash content of 17%. The use of Jameson Cell for flotation was also found helpless in improving the performance. The poor recovery of combustibles was attributed to low recovery of coarse particles (300m). Split processing involving spiral concentration of the coarser fraction (-500+100m) and Jameson Cell flotation of the -100-m fraction resulted in an improved overall performance. Substantial improvement in the yield of clean coal at the same target ash (17%) could be achieved in split processing.
