摘要/Abstract

摘要： 为了探究高效且环保的锂云母矿浮选分离药剂，通过纯矿物浮选试验，采用氯化钙作为活化剂，FL-2作为捕收剂，对锂云母、石英、钠长石纯矿物进行浮选分离研究，利用 Zeta 电位测试以及红外光谱进行机理分析，并将 FL-2+ Ca2+ 药剂组合实际应用于新疆某锂云母矿浮选开路及闭路试验中进行了验证。试验结果表明：捕收剂 FL-2 能够吸附在锂云母表面，而 Ca²⁺ 的存在能增加 FL-2 的吸附量；应用 FL-2+ Ca²⁺ 的药剂组合后，新疆某锂云母矿石浮选开路试验获得了 Li₂O 品位 3.30%、Li₂O 回收率 68.63% 的锂云母精矿，浮选闭路试验获得了 Li₂O 品位 3.06%、Li₂O 回收率 78.22% 的锂云母精矿，精矿产品质量符合指标要求。

Abstract: In order to explore efficient and environmentally friendly reagents for flotation separation of lepidolite，flotation separation of pure minerals of lepidolite，quartz and albite is studied by pure miner⁃ al flotation test，using calcium chloride as activator and FL-2 as collector.The mechanism analysis is car⁃ ried out by Zeta potential test and infrared spectroscopy. The FL-2+ Ca2+ reagent combination is applied and verified to the open-circuit and closed-circuit flotation tests of a lepidolite ore in Xinjiang. The results show that the collector FL-2 can be adsorbed on the surface of lepidolite，and the presence of Ca2+ can in⁃ crease the adsorption capacity of FL-2.After the application of FL-2+Ca2+ reagent combination，lepidolite concentrate with Li2O grade of 3.30% and Li2O recovery of 68.63% is obtained in the open-circuit flotation test of a lepidolite ore in Xinjiang，and lepidolite concentrate with Li2O grade of 3.06% and Li2O recovery of 78.22% is obtained in the closed-circuit flotation test. The product quality of the concentrate meets the index requirements.
