四川措拉锂多金属矿的矿物学特征研究

Mineralogical Study on Cuola Lithium Polymetallic Mining Area,Western Jijika,Sichuan

本文利用显微镜下鉴定、扫描电子显微镜(SEM)、X射线衍射分析(XRD)等分析测试手段对四川甲基卡西矿段的措拉锂多金属矿开展了详细的矿物学研究。研究结果显示,矿石矿物以锂辉石为主,少量的磷锂铝石、锂云母,副矿物为铌铁矿、铌钽铁矿、锡石等;脉石矿物以长石类、石英为主,次为云母类,副矿物有磷灰石、绿泥石等。矿石中锂主要赋存于锂辉石中,伴生有铌、钽、铷等有益组分,均达到综合回收利用。综上所述,该锂矿具有重要的开发利用价值。

Systematic mineralogical characteristics of Cuola lithium polymetallic mining area,western Jiajik rare metal ore gathering area,was studied in this paper.Known by analytical testing methods such as lake identification,scanning electron microscope(SEM),and X-ray diffraction analysis(XRD),the ore minerals are mainly spodumene,followed by very small amounts of phospatite,lithium mica,and trace amounts of niobite,niobite,and cassiterite.The gangue minerals are mainly feldspar and quartz,followed by mica,and trace minerals include apatite and chlorite.Lithium in the ore is mainly present in spodumene,with associated beneficial components such as niobium,tantalum,and hafnium,all reaching the comprehensive recovery index value;the mineral separation test shows that the major ore mineral such as spodumene can be used,in addition to,its associated valuable elements such as niobium and tantalum can also be realize comprehensive recovery and utilization,further indicating that the lithium mining area has important development value.
