高钼钨酸钠溶液萃取分离钨钼的研究

Study on the Solvent Extractive Separation of Tungsten and Molybdanum from Sodium Tungstate Solution Containing High Molybdanum

研究了在不加络合剂条件下，在硫酸体系中N263萃取分离钨钼的新工艺，考察了在单级分离过程中多因素的影响，得出了最佳条件．通过串级实验表明：反萃液（钨酸铵）Mo：WO3≤0.01％达到了分离质量要求。

Without adding complex reagents, the solvent extractive separation of tungsten and molybdamun by N263 in suiiuric acid system has been studied' The effect of manyfactors in the process of mono-step separation has been investigated, and the perfect conditions of separation has been found. Results of the multi-steps show that ratio of molybdamim to tungsten trioxide in stripping liquid (ammonium tungstate) is not more than 0.01percent and attained the quality demand for separation.
