PROCESSES FOR RECOVERING METALS FROM AQUEOUS SOLUTIONS

Japanese Patent JP2016053219

A

PROBLEM TO BE SOLVED: To provide processes for recovering value metals from aqueous solutions containing value metals, in particular Mo and U.SOLUTION: There is provided the processes for recovering Mo and/or other value metals (e.g., U) present in aqueous solutions from a large range of concentrations: from ppm to grams per liter via a solvent extraction process by extracting the Mo and/or other value metal from the aqueous solution by contacting an acidic aqueous solution containing value metals with an organic phase solution containing 5-(Calkyl)-2-hydroxyaryloxime, stripping the Mo and/or other value metal from the organic phase solution by contacting it with an aqueous phase strip solution containing an inorganic compound, and recovering the Mo and/or other value metal by separating it from the aqueous phase strip solution. When the Mo and/or other value metal are present only in low concentration, the processes include an organic phase recycle step and/or an aqueous phase strip recycle step in order to concentrate the metal prior to recover.SELECTED DRAWING: Figure 1
