利用甘肃天祝干沙鄂博稀土矿的最新勘查资料,选择内蒙白云鄂博、四川冕宁牦牛坪、山东郗山等3个典型轻稀土矿床,在列叙其资源储量、开发利用情况的基础上,主要从矿石特征、选冶性能两个方面进行了类比,认为天祝干沙鄂博稀土矿为单一轻稀土矿。主要稀土矿物氟碳钙铈矿的矿物粒度及解离度、矿石主组分REO品位等质量特征和矿石的选矿回收率、稀土精矿品位等选矿指标不及白云鄂博、牦牛坪和郗山,开发前应开展进一步的选冶性能及预可行性研究。
Based on the latest exploration data of Gansu Tianzhu dry sand Obo rare earth mine, three typical LREE deposits, including Baiyunebo in Inner Mongolia, Mianning Maoniuping in Shandong Province and Yushan Mountain in Shandong Province, are selected. On the basis of listing their reserves, development and utilization, Mainly from the characteristics of ore, dressing and smelting performance of two aspects of the analogy, think Tianzhu dry sand Ebo rare earth ore as a single light rare earth mine. The main rare earth mineral bastnaesite mineral size and degree of dissociation, the main components of the ore REO quality grade quality and ore beneficiation recovery rate, rare earth concentrate grade beneficiation indicators such as less than Bayan Obo, Maoniuping and Yanshan, development Pre-feasibility studies should be carried out further further refining and pre-feasibility studies.
