摘　　要：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 Ganshaebo rare earth ore of Tianzhu in Gansu province, through analogy with such three typical light rare earth ores as Bayan Obo of Inner Mongolia, Mianning of Sichuan and Chishan of Shandong from aspects of ore characteristics and dressing and smelting performance, this paper considers that it is single light rare earth ore. The mineral particle size, dissociation degree and REE grade of parasite quality characteristics and the indices of ore dressing recovery percentage and rare earth ore concentrate grade are inferior to Bayan obo, Maoniuping and Chishan typical light rare earth ore. In conclusion, this paper suggested that further performance and prefeasibility studies should be carried out before exploitation.
