摘要	党坝锂辉石矿床位于四川可尔因矿田的东南部,其Ⅵ号脉是矿区新发现的稀有金属伟晶岩脉,矿石研究程度低。为合理开发利用党坝锂辉石矿床锂资源并且为选矿工艺流程的制定提供理论依据,文章以党坝锂辉石矿床Ⅵ号脉锂辉石矿石为研究对象,采用显微镜下观察、电子探针(EPMA)、激光剥蚀等离子质谱(LA-ICP-MS)、X射线衍射分析(XRD)、矿物自动定量分析系统(TIMA)和矿物解离分析仪(MLA)等测试手段,开展了详细的工艺矿物学研究。结果显示,矿石中Li₂O含量为0.99%,锂辉石是主要的矿石矿物,脉石矿物主要为长石和石英,其次为云母。锂辉石晶体虽然粒度粗细不均,但是多集中在中粗粒范围内(320~1 280 μm),属于均匀较易解离矿石类型。矿石中锂主要赋存于锂辉石中,锂辉石中锂的配分比为97.80%,伴生有Nb、Be等有益组分且达到综合回收指标值。LA-ICP-MS实测锂辉石中Li₂O的平均含量为6.88%,锂辉石单矿物电子探针结果显示锂辉石中含有FeO(0.45%~0.73%),且少量Fe、Mn等杂质充填在锂辉石的解理、裂隙中,会一定程度上限制锂辉石精矿品级。
Abstract	Dangba spodumene deposit is located in the southeast of Sichuan Ke'eryin orefield. The No.Ⅵ vein is a newly discovered rare metal pegmatite vein in the mining area, and the ore research degree is low. In order to reasonably develop and utilize the lithium resources of the Dangba spodumene deposit and provide theoretical basis for the formulation of beneficiation process, the detailed process mineralogy research of the spodumene ore from No.Ⅵ vein of the Dangba spodumene deposit was studied by microscopic observation, electron probe microanalysis(EPMA), laser ablation plasma mass spectrometry (LA-ICP-MS), X-ray diffraction analysis (XRD), Tescan integrated mineral analyzer (TIMA), and mineral liberation analyzer (MLA). The results show that the content of Li₂O in the ore is 0.99%, the main ore mineral is spodumene, while the gangue minerals mainly include feldspar and quartz, followed by mica. Although the particle size of spodumene crystals is uneven, they are mostly concentrated in the range of medium to coarse particles (320~1 280 μm), which belongs to the ore type that is homogeneous and easy to dissociate. Lithium mainly occurs in spodumene, with a lithium-partition ratio of 97.8%. Nb and Be are associated with lithium and reach the comprehensive recycling indices. The mean content of Li₂O in spodumene is 6.88% by LA-ICP-MS. The spodumene contains FeO (0.45%~0.73%) by EPMA, and a small amount of impurities such as Fe and Mn and other are filled in the cleft and cracks of spodumene, which will limit the grade of spodumene concentrate.
