Abstract

The dependence of tungsten leaching and solution purification processes on solution composition is treated in terms of aqueous phase diagrams (such as Eh-pH, log Metal-pH, log Anion-pH) generated with the DIAGRAM computer program. The systems considered are W-H₂O, Me-W-H₂O, Me-W-CO₃-H₂O, Mo-H₂O, Me-Mo-H₂O (Me = Ca, Mn, Fe); S-H₂O, W-S-H₂O, and Mo-S-H₂O. These diagrams are examined in the context of selective dissolution of tungsten from scheelite and wolframite.
