Electric separation utilizes different conductivity of mine and vein mineral grain, can process electric classification and separation in high voltage electric field. It is effective method to separate tungsten and tin in tungsten scheelite. But it is also used in tungsten concentrate gravity separation.

Tungsten scheelite electric separation can separate tungsten and tin. In nature, tungsten is always accompanied by tin. Their density is almost the same and is hard to be taken apart. In the past, flotation method or high temperature chloride volatilization method are used, but there exists some shortcomings.

Tungstate consists of wolframate radical or poly tungsten acid radical. Ammonium ions, alkali metals, alkaline earth metals and many heavy metal cations can form tungstates. Apart from alkali metal, ammonium and magnesium salts, most tungstate is insoluble in water.

After artificial beneficiation, tungsten concentrate will enter gravity separation process. Crush means crushing tungsten concentrate into same specification before it goes to the next step. This needs to be completed with crusher.

Tungsten concentrate is mild magnetic mineral, under certain grinding, it can adjust magnetic intensity or change selection medium to absorb tungsten concentrate on the magnetic medium to realize separation with mineral vein.

Mechanical agitated flotation machine is the use of impeller + stator system as a mechanical stirrer to achieve the filling and stirring flotation machine, is the most commonly used tungsten scheelite flotation equipment.

Flotation column is a new type of tungsten scheelite flotation equipment, it has a simple structure, small footprint, low cost, high degree of automation, low infrastructure investment, good flotation index and many other advantages, and gradually become mainstream in tungsten ore flotation.
