摘　　要：以宜春钽铌矿重选尾矿中锂云母为研究对象,开展组合捕收剂浮选锂云母的试验研究。结果表明,自配药剂LZ-00与椰油胺以质量比2∶1组合浮选锂云母时指标最好,最佳总药剂用量为360g/t。在该药剂制度下,采用1粗1精1扫的简单流程可得到Li2O品位4.12%、回收率70.37%的锂云母精矿,与现场指标相比有较大程度提高。通过红外光谱分析可知,LZ-00与椰油胺组合浮选时在锂云母矿物表面有化学吸附和物理吸附,同时还存在氢键作用。Application of combined collectors in flotation of lepidolite were researched, and the object is the gravity concentration tailing of Yichun Tantalum ＆ Niobium mine. The experiments showed： when LZ-00 dispensed by ourselves and mixed amine combined with mass ratio of 2：1 was used in lepidolite flotation, the flotation indexes is the best, and the optimum dosage is 360 g/t. Using the combined collector and the flotation flowsheet of one roughing, one cleaning and one scavenging got the lepidolite concentrate with grade 4.12%, recovery 70.37%. It had a remarkable upgrading compared with the target of ore dressing plant. Infrared spectrum showed mineral surface existed chemical adsorption and physical adsorption and hydrogen bonding simultaneously when using LZ-00 and mixed amine to flotation lepidolite.
