mineral processing scheelite

Scheelite - Wikipedia

Scheelite is a calcium tungstate mineral with the chemical formula Ca W O 4.It is an important ore of tungsten (wolfram). Well-formed crystals are sought by collectors and are occasionally fashioned into gemstones when suitably free of flaws. Scheelite has been synthesized using the Czochralski process; the material produced may be used to imitate diamond, as a scintillator, or as a solid ...

May 01, 2018· When coarse, scheelite can be concentrated by gravity separation. However, as a brittle mineral (hardness of 4.5–5 on Mohs scale), it tends to slime easily during comminution. Finely grained scheelite is usually processed with froth flotation, which has only been the way to go since the 1970s .
