Froth flotation of scheelite – A review - ScienceDirect

May 01, 2018  1. Introduction. Scheelite (CaWO 4) is one of the main sources of tungsten, alongside with the other monotungstates stolzite (PbWO 4) and wolframite (a solid solution of ferberite (FeWO 4) and hübnerite (MnWO 4)).Scheelite is however more common and is found in approximately 65% of known tungsten deposits .Pale white to brown-orange, scheelite’s main characteristic is its blue color
