稀土精矿中钍的提取工艺研究进展

Progress in Extraction Technology of Thorium from Rare Earth Concentrate

核能开发是我国能源战略和经济发展的重要举措,发展核能离不开核燃料。钍是一种重要的核燃料,在核能开发方面具有广阔的应用前景,能有效解决我国能源紧缺等问题。钍极少以独立矿物赋存,大多与稀土矿物共生。主要对近年来稀土精矿中钍的提取工艺研究进展进行了综述,并对稀土精矿中稀土和钍的综合利用发展提出了相关建议。

Nuclear power development was an important measure of Chinese energy strategy and economic development, which could not be separated from the nuclear fuel. Thorium was an important nuclear fuel, which had broad application prospects for nuclear pow- er, so it could effectively solve the shortage of energy in China. Thorium was rarely independent existence in ores, mostly associated with rare earths. The research progress on the extraction technology of thorium from rare earth concentrate in recent years was reviewed. The multipurpose use and development of rare earth and thorium in rare earth concentrate resources were also proposed and suggested.
