【摘要】 湖北随州霞石正长岩经破碎筛分后 ,分别采用干式和湿式磁选工艺流程脱除含铁矿物 ,达到了霞石正长岩除铁提纯的目的 ,可以从含FeO (全铁氧化物含量 ) 6 .44%的原矿中获得FeO <0 .8%的霞石正长岩精矿。更多还原

【Abstract】 The dry and wet magnetic separation are adopted respectively to separate iron minerals from the nepheline syenite after crushing and screening. The testing process and results of the separation are introduced. The FeO(all of iron oxide) content of nepheline syenite concentrate is to less than 0.8% from 6.44% of the original.更多还原
