| Abstract: | Renli extra-large Ta-Nb deposit is rich in tantalum, niobium and beryllium resources. The Ta2O5 resource is of extra-large scale and the Ta2O5 resource reaches large scale. In order to further study the occurrence characteristics, metallogenic regularity and the prospect of comprehensive utilization of mineral resources of rare metals in Renli extra-large Nb-Ta deposit, the authors have carried out the research work of geochemical analysis, EPMA, fluid inclusion study, isotope dating and mineral processing experiment. Based on the systematic review of the research progress in Renli extra-large Ta-Nb deposit, the authors also discussed the following prospectiong ideas of the deposit. There are many associated minerals in Renli Nb-Ta deposit, and the recovery rate of rare metals and the comprehensive utilization rate of mineral resources are high. Therefore it has great value of development and utilization, and the efficient exploration and development that characterized by green, environmentally friendly and no tailings can be carried out in Renli Ta-Nb deposit as a typical example. Renli mining area is rich in tantalum, niobium and beryllium resources and has great prospecting potential. With increasing geological exploitation funding, it’s probable to make new prospecting progress of Ta-Nb-Be-Li rare metal. The next work will focus on the control of the deep ore bodies of No.2, 3, 5 and 6 main ore veins in the mining area in order to make new progress in tantalum niobium beryllium ore prospecting. The research work of concealed spodumene muscovite albite pegmatite in western or southwestern mining area will be strengthened in order to make a breakthrough in spodumene muscovite albite pegmatite type lithium ore prospecting. |
