我国锂辉石矿的工艺矿物学特征及其对浮选行为的影响

Process Mineralogy Characteristics of Spodumene Ore in China and Its Effect on Flotation Behavior

为了给我国锂矿石资源的高效开发利用提供指导,在总结我国锂辉石矿的矿石成分、结构构造、主要矿物嵌布特征的基础上,进一步分析了我国锂辉石矿石的工艺矿物学特征对选矿的影响。结果表明,松潘—甘孜成锂带、阿尔泰成锂带锂辉石矿石Li_(2)O品位较高,以块状构造为主,锂辉石嵌布粒度较粗,有利于获得较好的浮选指标;秦岭成锂带、华南成锂带锂辉石矿石Li_(2)O品位较低,锂辉石嵌布粒度较细,开发利用难度较大,生产成本较高。根据我国锂辉石矿石的工艺矿物学特征,建议重视四川、新疆的锂辉石矿石的高效综合利用。

In order to provide guidance for the efficient development and utilization of spodumene ore resources in China,based on the conclusion about the ores composition,texture,structure,main mineral embedded characteristics for the spodumene ore in China,the influence of process mineralogy characteris⁃tics on flotation was further analyzed.The results showed that the spodumene ores of Songpan-Garze lithi⁃um mineralization belt and Altay lithium mineralization belt have higher Li_(2)O grade,and their structures are mainly massive structure.The embedded particle sizes are coarse,which is conducive to obtaining bet⁃ter flotation indexes.The spodumene ores in Qinling lithium mineralization belt and Southern China lithium mineralization belt have lower Li_(2)O grade,and their embedded particle sizes are fine.Therefore,it is diffi⁃cult to develop the ores and production cost is larger.According to the process mineralogy characteristics of spodumene in China,it is suggested to pay more attention to the efficient and comprehensive utilization of spodumene in Sichuan and Xinjiang.
