摘　　要：研究了某霞石正长岩的矿物特性，弄清了铁在矿石中的赋存状态。试验结果表明多段干式磁选工艺是除去该矿石中铁矿物的有效途径。当原矿含铁为２．９８％时，通过分选可以获得产率为７４％，含铁量低于０．The existence state of iron in nepheline syenite somewhere and the technology of separation of iron from the ore were studied. The yield of nepheline syenite is up to 74% and iron content in the concentrate is 0.2% below (2.98% Fe in the original sample) with the technology of stages dry magnetic seperation.
