摘　　要：根据煤与煤系黄铁矿磁性的差异,利用高梯度磁选工艺脱除黄铁矿硫。利用Slon-100磁选机进行了细粒煤脱硫试验,在热量回收率为91.38%时,脱硫率和脱灰率分别达到40.80%、52.62%;在热量回收率为74.88%时,脱硫率和脱灰率分别达到56.34%、62.97%。Sulfur of the coal can be desulfurized by high grids megnitic system, because the magnetism of the coal and that of the pyrite are different. The desu lfurization test is achieved by Slon-100 HGMS. When percent of the received qua ntity of the heat is 91.38%, the percent of the desufurization is 40.80%, the percent of the ash decrease is 52.62%; When percent of the received quantity of the heat is 74.88%, the percent of the desufurization is 56.34%, the percent of the ash decrease is 62.97%.
