摘　　要：对云浮低品位硫铁矿矿石进行重选试验研究,当原矿约含硫28%、粒度小于4 mm时,采用分级后粗粒跳汰-细粒螺旋选别的重选流程,可以得到最终硫精矿品位37.11%,硫回收率84.06%的选别指标,为低品位硫铁矿矿山的开发指出了一条新路子.Our gravity separation research has been carried out in the Yunfu low-grade pyrite ore. A conc-entrate grading of 37.11% sulfur with a sulfur recovery rate of 84% was obtained from a run-of-mine ore containing 28% sulfur with size less than 4 mm by using a simple gravity flowsheet. The ore was screened into two parts in the process, i.e. the coarse grain was separated by jigger and the fine one was separated by spiral. An alternative approach was therefore developed for the low-grade pyrite mines.
