Abstract

Abstract

Systematic research of mineralogical characteristics of spodumene of VIII pegmatite vein in Dangba spodumene deposit are studied by microscopic observation, electron probe micro analysis (EPMA), Laser ablation plasma mass spectrometry（LA-ICP-MS）and X-ray diffraction analysis (XRD). The results show that the main ore mineral is spodumene. The spodumene crystal partical is large, lithium mainly occurs in spodumene, accompanied by niobium and tantalum beneficial components. XRD and LA-ICP-MS analysis show that the purity of spodumene is very high（the average contentof Li₂O is 7.84%）and the cell parameters are slightly lower than those of standard cards. The EPMA results show that the content of SiO₂ in spodumene was high (65.62%~65.82%), with a small amount of impurities such as Fe and Mn. The contents of Li₂O in the pegmatite ore is up to 1.33%. To sum up, the lithium ore has important development and utilization value.
