    Abstract: Provided herein are processes for recovering molybdenum and/or other value metals (e.g., uranium) present in aqueous solutions from a large range of concentrations: from ppm to grams per liter via a solvent extraction process by extracting the molybdenum and/or other value metal from the aqueous solution by contacting it with an organic phase solution containing a phosphinic acid, stripping the molybdenum and/or other value metal from the organic phase solution by contacting it with an aqueous phase strip solution containing an inorganic compound and having a

    Abstract translation: 本文提供了通过萃取钼和/或其它有价金属,通过溶剂萃取过程从大ppm浓度范围内回收存在于水溶液中的钼和/或其他有价值的金属(例如铀)的方法:从ppm到克每升 通过使水溶液与含有次膦酸的有机相溶液接触,从有机相溶液中汽提钼和/或其它有价值的金属,通过使其与含有无机化合物且具有<1.0M 游离氨的浓度,以及通过将其与水相条溶液分离而回收钼和/或其他有价值的金属。 当钼和/或其他有价值的金属仅以低浓度存在时,所述方法可以包括有机相再循环步骤和/或水相带再循环步骤,以在回收之前浓缩金属。
