摘要: 为了提升某锂辉石矿的开发利用效率,针对该锂辉石矿物组成复杂、分选难度大等问 题,在矿石性质研究的基础上,开展了脱泥与不脱泥条件下的浮选工艺对比试验。试验结果表明:在 磨矿细度为-0.074 mm70%,调整剂碳酸钠+氢氧化钠用量(1 000+300)g/t,活化剂氯化镁用量150 g/t, 组合捕收剂 BK452A+BK452B用量(1 200+800)g/t的条件下,不脱泥,采用 1粗 3精 1扫工艺流程,闭 路试验获得了 Li2O 品位 5.71%、Li2O 回收率 85.52% 的锂辉石精矿,为该类矿石的高效开发提供了技 术支撑。

Abstract: In order to improve the development and utilization efficiency of a spodumene mine,aim‐ ing at the problems of complex mineral composition and difficult separation of the spodumene,based on the study of ore properties,a comparative test of flotation process under desliming and non-desliming condi‐ tions is carried out.The results show that under the conditions of grinding fineness of -0.074 mm 70%,dos‐ age of adjusting agent sodium carbonate + sodium hydroxide(1 000+300)g/t,dosage of activator magne‐ sium chloride 150 g/t,dosage of combined collector BK452A+BK452B(1 200+800)g/t,without deslim‐ ing,spodumene concentrate with Li2O grade of 5.71% and Li2O recovery of 85.52% is obtained by closed�circuit test with one roughing,three cleaning and one scavenging process,which provides technical support for the efficient development of this kind of ore.
