Abstract:
Provided are methods method of recovering metal from an aqueous solution, the method comprising contacting an aqueous solution containing at least two metals selected from molybdenum, cobalt, nickel, zinc and iron with an organic solvent and an oxime-containing reagent composition at a predetermined pH, the predetermined pH selected to provide a high first metal extraction and a low second metal extraction; and separating the first metal from the solution.
