Experimental research on desulphurization of fine coal using a centrifugal dense medium separation
Abstract：The desulphurization and deash effect for --500 μm different size fraction Nantong fine coal were studied in the Falcon centrifugal dense medium separator. Four indexes inclu- ding, the recovery of combustibles, deash rate, desulphurization rate and desulphurization effi- ciency were used to analysis the separation efficiency of Nantong high sulphur content coal by Falcon centrifugal dense medium separator and froth flotation, respectively. The results show that the deash rate by Falcon separation is lower than that by flotation for --500 /~m coal, and the other indexes are all higher than that by flotation. The size of 125 ~m is the significant de- marcation point. The deash and desulphurization rate by Falcon separator are all better than that by flotation for 500--125μm coal. For -125μm coal, The deash and desulphurization rate by Falcon separator are all lower than that by flotation, and the recovery of combustibles is higher than that by flotation.
