西北某铁选厂处理的铁矿石含铁33.77%，主要有用矿物为镜铁矿、褐铁矿、菱铁矿，嵌布粒度粗细不均，属于国内典型的复杂难选矿石。为了回收-15 mm粒级粉矿，采用了SLon-2500立环脉动高梯度磁选机，试验结果表明，立环强磁粗选精矿品位达到46.70%，已经达到强磁精矿设计指标，可作为最终强磁精矿；扫选尾矿品位达到19.00%，可以作为尾矿抛除；-0.02 mm含量占95.90%的细颗粒采用立环强磁进行粗选，所得精矿品位及回收率分别达到42.16%、53.12%，尾矿品位达到19.76%，精矿品位提高了13.21个百分点。 SLon-2500立环脉动高梯度磁选机能够对该选厂铁矿物进行全粒级回收。
西北某鐵選廠處理的鐵礦石含鐵33.77%，主要有用礦物為鏡鐵礦、褐鐵礦、蔆鐵礦，嵌佈粒度粗細不均，屬于國內典型的複雜難選礦石。為瞭迴收-15 mm粒級粉礦，採用瞭SLon-2500立環脈動高梯度磁選機，試驗結果錶明，立環彊磁粗選精礦品位達到46.70%，已經達到彊磁精礦設計指標，可作為最終彊磁精礦；掃選尾礦品位達到19.00%，可以作為尾礦拋除；-0.02 mm含量佔95.90%的細顆粒採用立環彊磁進行粗選，所得精礦品位及迴收率分彆達到42.16%、53.12%，尾礦品位達到19.76%，精礦品位提高瞭13.21箇百分點。 SLon-2500立環脈動高梯度磁選機能夠對該選廠鐵礦物進行全粒級迴收。

The refractory iron ore with TFe grade of 33 . 77% form a northwest dressing plant con-tains useful iron minerals as specularite, limonite, siderite, and the size distribution of iron ore is nonuniform. SLon-2500 vertical ring pulsating high gradient magnetic separator was used to sepa-rate the iron ore of -15 mm. And the results showed that the Fe grade of the magnetic rougher con-centrate is up to 46. 70%,which met design index for the rougher concentrate. The scavenging con-centrate with Fe grade of 19. 00% was removed as tails. The Fe grade and recovery of magnetic rougher concentrate of fines were 42. 16% and 53. 12% respectly,and the Fe grade of concentrate increased by 13. 21 percentage points,and the Fe grade of tails was 19. 76%. SLon-2500 Magnetic Separator can be use to separate the whole size iron ore.
