摘要

摘要:
这是一篇矿物加工工程领域的论文。新疆某锂辉石矿Li₂O品位为1.04%，含锂矿物主要为锂辉石、含锂白云母及磷锂铝石，脉石矿物主要有石英、钠长石和钾长石。该矿石在磨矿细度-0.074 mm 79.4%的条件下，采用自主开发的捕收剂EM-PN51，经一粗一扫三精的浮选闭路流程，最终获得Li₂O品位5.36%、Nb₂O₅含量0.071%、Ta₂O₅含量0.044%的含铌钽锂精矿，Li₂O回收率为87.38%，Nb₂O₅回收率为87.33%、Ta₂O₅回收率为88.26%，实现了该锂辉石矿中多种有价组分的综合回收。

Abstract:
This is an essay in the field of mineral processing engineering. Li₂O grade of a spodumene ore in Xinjiang is 1.04%. The lithium-containing minerals are mainly spodumene, Lithium-Muscovite and montebrasite. The gangue minerals are mainly quartz, albite and potassium feldspar. Under the condition of grinding finness -0.074 mm content 79.4%, using self-developed collector EM-PN51, the concentrate productswith Li₂O grade 5.36%, Nb₂O₅ content 0.071%, Ta₂O₅ content 0.044% and Li₂O recovery rate 87.38%, Nb₂O₅ recovery rate 87.33%, Ta₂O₅ recovery rate 88.26% can be obtained bythe closed flotation circuit of one-roughing, one-scavenging, three-cleaning. The comprehensive recovery of several valuable components in spodumene ore is realized.
