摘要:
刚果(金)某锂辉石Li2O品位0.86 %，属于低品位难选锂矿石。为实现该锂辉石高效综合利用，对其开展浮-磁联合试验研究。研究结果表明：在磨矿细度-0.074 mm占比75.0 %，碳酸钠用量500 g/t，氯化钙用量140 g/t，氢氧化钠球磨机内用量700 g/t、浮选槽内用量200 g/t，捕收剂组合A（氧化石蜡皂与油酸质量比为1∶3）用量1 650 g/t条件下进行一粗两扫三精一磁闭路试验，可获得Li2O品位为5.67 %、Li2O回收率为77.71 %的脱磁产品，Li2O品位为4.51 %、Li2O回收率为10.51 %的磁性产品。试验指标良好，为锂辉石资源综合利用提供重要参考依据。

Abstract:
A spodumene from the Democratic Republic of Congo (DRC) has a Li2O grade of 0.86 %,classifying it as a low-grade and refractory lithium ore.To achieve efficient and comprehensive utilization of this spodumene,a joint flotation-magnetic separation test was conducted.The results indicate that under the conditions of grinding fineness of -0.074 mm accounting for 75.0 %,the addition of 500 g/t sodium carbonate,140 g/t calcium chloride,700 g/t sodium hydroxide in the ball mill,and 200 g/t sodium hydroxide in the flotation cell,along with 1 650 g/t of reagent combination A (a mixture of oxidized paraffin soap and oleic acid in a mass ratio of 1∶3),a closed-circuit test with roughing once,scavenging twice,cleaning three times,and magnetic separation once produced a non-magnetic product with a Li2O grade of 5.67 % and a Li2O recovery rate of 77.71 %.Additionally,a magnetic product with a Li2O grade of 4.51 % and a Li2O recovery rate of 10.51 % was obtained.The test results are favorable,providing a valuable reference for the comprehensive utilization of spodumene resources.
