The isomorphism of tungsten and molybdenum is strong in scheelite-type ores but quite limited or even not existent in wolframite.
These differences inspired us to develop some new separation methods by imitating the formation of wolframite, for the precipitation processes are similar to the mineralization processes.
Through experimental studies, the reliability of such ways was verified by the precipitation behaviors of W and Mo with different divalent ions.
Furthermore, MnSO4 was chosen as a valuable reagent for the separation and then effects of several variables were evaluated. The results showed that this method worked well in the neutral solution.
