How to extract tungsten from scheelite ore

Scheelite is a calcium tungstate mineral with the chemical formula CaWO4. It is an important ore of tungsten.

Scheelite minerals are generally in the friable class and therefore concentrating processes are hindered by the excess amount of fines produced in the crushing and grinding steps. Special consideration must be given to the stage reduction and concentration to avoid excessive losses in the fines.

The Mineral Jig plays an extremely important role in this flowsheet due to its ability to handle an unclassified feed, with outstanding recovery in the coarse sizes and substantial recoveries in the fine sizes. A selective high grade product is obtained with a minimum amount of water.

The idea behind a jig is that particles are introduced to a jig bed (usually a screen) and then thrust upward within a water column. The particles are thus suspended within the water and once the pulse dissipates, the particles settle again, those with higher density faster than the ones with low density. The repeated jigging action leads thus to a separation of the higher and lower-density particles on the jig bed, from where the density concentrate can be removed.
