Leaching of tungsten in the ore-dressing products of scheelite by various carboxylic acids revealed that oxalic acid leaches tungsten quantitatively. Powdered scheelite samples of Γ”200 mesh size were decomposed with 4% oxalic acid at 100 Γ„C with constant stirring for 1 h. Tungsten was determined by
