前言微山稀土矿是我国特有的一种以铈族元素为主,中等规模的稀土金属矿床,该矿矿石及脉石矿物简单,单矿物以氟碳钙铈矿及氟碳铈矿为主,矿石选矿性能好。因该矿床不同于其他类型的稀土矿床,所以积极开发微山稀土矿,充分发挥其资源独特的优势,对促进我国稀土工业的发展是有重要意义的。地质资料表明,该矿伴生有少量天然放射性元素铀、钍。钍元素以单矿物钍石为主,其 Introduction Weishan rare earth ore is a peculiar type of rare earth elements dominated by cerium in China. The ore and gangue minerals are simple and the single minerals are mainly bastnasite and bastnaesite. Good ore dressing performance. Because the deposit is different from other types of rare earth deposits, actively developing the Weishan rare earth mine, give full play to its unique advantages of resources, to promote the development of China’s rare earth industry is of great significance. Geological data show that the mine associated with a small amount of natural radioactive elements uranium, thorium. Thorium single mineral thorium-based, its
