低品位鲕状褐铁矿风选试验研究

Research on the Wind Separation of Low-Grade Oolitic Limonite Ore

本试验以海南儋州鲕状褐铁矿为试样,原矿品位40.15%,重点对此矿石进行了风选的可选性研究。再配以焙烧—磁选,最终得到了铁品位56.55%,回收率84.50%的铁精矿。一定程度上避免了褐铁矿选矿时产生的严重泥化现象,节水节能。

The feasibility study was made on the beneficiation of Hainan Danzhou oolitic limonite ore grading 40.15% mainly by wind separation. An iron concentrate grading 56.55% at a recovery of 84.50% was finally obtained with the help of roasting -magnetic separation. The process can avoid the serious sliming of limonite ore processing to some extent, and save the water and energy.
