本文就近年国外有关稀土金属工业环境污染问题及其处理方法,对在稀土金属工业生产过程中如何防止稀土金属及放射性污染问题,进行了初步探讨。一、环境中的稀土进入环境中的稀土化合物大部分均来自天然岩石的风化作用。在矿物燃料中含有少量稀土元素化合物, 如煤中镧、铈、钇含量均可在10ppm以 In this paper, foreign countries in recent years, rare earth metal industry environmental pollution problems and treatment methods, rare earth metals in the industrial production process how to prevent rare earth metals and radioactive contamination problems were discussed. First, the environment of rare earth Most of the rare earth compounds into the environment are from the natural rock weathering. In the fossil fuel contains a small amount of rare earth compounds, such as coal lanthanum, cerium, yttrium content can be 10ppm
