| 英文摘要 | The chemical composition, mineral composition, occurrence state of niobium and niobium minerals' dissemination characteristics of Nb-bearing mineral raw materials of Bayan Obo were investigated by means of mineral liberation analyzer(MLA), X-ray diffraction, scanning electron microscope, energy disperse spectroscopy and chemical analysis. The research results show that the chemical and mineral composition of the raw materials are complex, of which the grade of niobium and the total mass fraction of rare earth oxide are 1.10% and 1.37%, respectively. The main niobium minerals are nioboaeschynite, ilmenorutile, pyrochlore, dingdaohengite, mangancolumbite, niobite, baotite, and fergusonite, in which the highest mass fraction of nioboaeschynite, the highest mass fraction of niobium in mangancolumbite, and the highest metal distribution rate of niobium in nioboaeschynite are 1.84%, 54.34%, and 44.85%, respectively. The particle size of niobium minerals is relatively fine. Except nioboaeschynite, the liberation degrees of the rest niobium minerals are relatively low, which are mainly attached with riebeckite and iron oxide. From the perspective of process mineralogy, only by solving the problems of efficient enrichment of micro fine-grained niobium minerals and separation of Nb/Ti in raw niobium-bearing mineral materials could the goal of efficient and comprehensive utilization of Bayan Obo niobium mineral resources be achieved. 漏 2021, Editorial Department of Journal of Northeastern University.
