Fine Coal Dewatering

Fine coal constitutes a relatively small portion of a product stream in a coal cleaning plant However, its processing cost is approximately three times higher than the cost of processing coarse coal Therefore, many coal companies chose to discard the fines to refuse ponds, causing a loss of profit and creating environmental concerns...

Fine coal beneficiation by column flotation

The amenability of beneficiating a fine hard coal from Hwa-Sun coal mine using column flotation has been studied using a CoalPro flotation column developed by Canadian Process Technologies (CPT) After initial testwork using a batch flotation cell to determine the optimal flotation conditions, tests were carried out to compare its performance with the column...
