摘　　要：蓝晶石是耐火材料的重要原料之一,广泛应用于冶金、建材和其他工业部门。因其原矿中常含有铁,致使影响其工业价值。河北某地蓝晶石矿在磨矿细度-0.074mm占65%、脉动冲程25mm、作业浓度为30%、脉动冲次320次/min,磁感应强度16000Oe的情况下,有效去除了矿石中的含铁杂质。LGS系列立式感应湿式强磁选机在现场连续运转30个工班,产品指标比较稳定。对强磁尾矿进行分析,Al2O3含量为22.38%,含铁为1.56%,其中Al2O3的回收率为42.66%,为后续分选创造了条件。The kyanite is one of fire-proof material important raw materials,the widespread application in other metallurgies,building materials and industry sectors,because of it includes the iron,causes to affect its commercial value.Some Hebei kyanite quarry in rubbing degree of fineness-0.074mm accounts for 65%,pulsation stroke is 25mm,the pulp mass concentration is 30%,the pulsation to 320 per minute,in the magnetic induction intensity 16000 Oe situations,can remove the iron impurity in ore effectively.LGS series vertical induction wet strong magnetic ore separator at the scene continuous working 30 labor classes,the product target is quite stable.Analysis of strongly magnetic tailings,the Al2O3 content are 22.38%,the iron is 1.56%,the Al2O3 returns-ratio is 42.66%,has created the condition for the following separation.
