非洲某锂辉石矿分选工艺

    Separation Technology of a Spodumene Ore in Africa

    • 摘要: 这是一篇矿物加工工程领域的论文。非洲某伟晶岩锂矿中有用矿物以锂辉石为主,原矿Li2O含量为0.87%,属低品位锂矿,开发利用相对困难。本研究通过详细的浮选实验,采用“一粗二扫三精”的浮选工艺,获得了产率为10.15%的锂辉石精矿,含Li2O 6.03%,锂回收率70.14%。磁选除杂实验结果表明,锂浮选精矿经0.2 T磁选可获得化工级-1锂辉石精矿产品,经0.6 T磁选可获得陶瓷级锂辉石精矿产品,实现了该低品位锂矿的高质化利用。

       

      Abstract: This is an essay in the field of mineral processing engineering. The useful mineral of a pegmatite lithium deposit in Africa is spodumene, and the raw ore contains 0.87% Li2O. It belongs to low-grade lithium ore, which is relatively difficult to develop and use. In this study, a spodumene concentrate with a yield of 10.15%, containing 6.03% Li2O and lithium recovery of 70.14% was obtained through detailed flotation tests and the flotation process of "one roughing, two scavengings and three cleanings". The magnetic separation test results show that chemical grade -1 spodumene concentrate can be obtained by 0.2 T magnetic separation of lithium flotation concentrate, and ceramic grade spodumene concentrate can be obtained by 0.6 T magnetic separation of lithium flotation concentrate, which realizes the high-quality utilization of this low-grade lithium ore.
