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.
