Extraction separation of W and Mo is a technical problem in tungsten metallurgy. For a long time, lots of methods have been researched by the scholars at home and abroad, such as solvent extraction, precipitation, ion-exchange and so on. Solvent extraction is an efficient method and active research filed for W/Mo separation. At present, solvent extraction is still in research stage, and could not meet the needs of industrialization. The extraction separation of tungsten and molybdenum in the past decades is briefly reviewed and commented. By contrasting and analyzing the characteristics of various kinds of extraction separation method, it is indicated that the research fields, such as investigating the difference of the chemical and physical properties of tungsten and molybdenum compounds, difference of the coordination compound properties of tungsten and molybdenum in redox system, new type of high effective extractant and extraction system for achieving effective W/Mo separation, are the important research directions.%钨钼分离是钨冶金中的一个技术性难题,长期以来,国内外学者围绕钨钼分离进行了大量研究,采用的方法有很多,如萃取法、沉淀法、离子交换法等.溶剂萃取法是一种深度分离钨钼的有效方法,也是钨钼分离研究中的一个非常活跃的领域.当前萃取法分离钨钼仍处在研究阶段,离工业化仍有距离,本文对几十年来萃取法分离钨钼的研究进展进行了简单的回顾和评述,对比和分析各种萃取分离方法特点,指出加强研究钨钼化合物物理化学性质差异、钨钼氧化还原体系配合物性质差异、新型高效萃取剂与新型萃取体系以达到钨钼的深度分离,是值得研究的方向.
