摘要: 某花岗伟晶岩型锂辉石矿矿物组分复杂、嵌布粒度细,为了寻找合理的选矿工艺流程, 针对该矿石开展了2 个不同选矿流程的试验研究。试验获得了锂精矿Li2O品位5.64%、锂金属回收 率78.10%的选别指标;得出优先剔除矿泥和云母,对改善后续锂辉石浮选指标非常有益,对于该矿石 采用阶段磨选—粗精矿再磨—精选流程比连续磨矿—脱泥—浮选流程,无论是在选别指标上,还是 流程结构上均更有优越性。

Abstract: The mineral composition of a granite pegmatite spodumene ore is complex and the embedded particle size is fine. In order to find a reasonable beneficiation process,two different beneficiation processes were carried out on the ore. The separation index of lithium concentrate with Li2O grade of 5.64% and lithium metal recovery of 78.10% was obtained by the test. It is concluded that the preferential removal of slime and mica is very beneficial to improve the subsequent spodumene flotation index. For the ore,the stage grinding-rough concentrate regrinding-concentration process is superior to the continuous grindingdesliming- flotation process both in terms of separation index and process structure.
