中国稀土冶炼提纯能力全球第一 但这是付出了代价的
当时，国际上主流的分离方法是“离子交换法”和“分级结晶法”，但这两种方法成本很高，提炼的稀土元素纯度很低，不适合大规模生产。 徐光宪提出新方案，“串级 稀土冶炼方法有两种，湿法冶金和火法冶金。 稀土湿法冶金属化工冶金方式，全流程大多处于溶液、溶剂之中，如稀土精矿的分解、稀土氧化物、稀土化合物、 稀土工业技术简析

关于稀土的萃取工艺
随着磷矿资源不断利用，正转向低品质磷矿的开发，硫酸湿法磷酸工艺成为磷化工主流方法，对硫酸湿法磷酸中的稀土进行回收已成为研究热点。. 在硫酸湿法磷酸生产过程中，通 1972年，一个中国人开始研究稀土分离提纯技术，他叫徐光宪，当时已经52岁。. 他原本是从事核燃料研究，后来发现稀土金属被国外垄断，便转变科研方向。. 科工力量：中国获得稀土冶炼提纯能力，是付出了代价的
