现在,溶剂萃取已是一种众所周知的湿冶方法,它已不再限于核方面和一些象锆、铪和铌、钽等稀有金属使用的方法,而且已成为有色金属和稀土金属的一种重要的金属离子分离、净化和富集的湿冶方法,其发展速度也在剧增,如果在萃取剂和设备上不断改进,则将 Solvent extraction is now a well-known wet-smelting process that is no longer limited to nuclear and some methods of using rare metals such as zirconium, hafnium and niobium, tantalum, etc., and has become an important non-ferrous and rare earth metal Of the metal ion separation, purification and enrichment of the wet smelting method, its rate of development is also increasing rapidly, if the extractant and equipment on the continuous improvement, will be
