Patent number: 8328900Abstract: 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 ?1.0 M concentration of free ammonia, and recovering the molybdenum and/or other value metal by separating it from the aqueous phase strip solution. When the molybdenum and/or other value metal are present only in low concentration, the processes can include an organic phase recycle step and/or an aqueous phase strip recycle step in order to concentrate the metal prior to recover.Type: GrantFiled: July 6, 2010Date of Patent: December 11, 2012Assignee: Cytec Technology Corp.Inventors: Troy Allan Bednarski, Violina Antoneta Cocalia, Matthew Dean Soderstrom, Eduardo Alberto Kamenetzky, Andrew Michael Cameron, Douglas Harris
