Tungsten scheelite flotation equipment usually includes mechanical agitated flotation machine and jet flotation machine. In recent years, with the continuous progress of the process, a new type of flotation equipment also added to the flotation equipment team, it is the flotation column.

Spiral chute beneficiation utilizes the water current flow from slope into chute, under vertical movement to separate ore and grit. It utilizes different proportion and density to separate mine and gangue mineral. In recent years, it has gradually taken place of tabling beneficiation.

Amphoteric collector is a heterogeneous organic compound with both anions and cations in the molecule. The common used collectors include a-amino fatty acid, alkyl phosphate (salt), alkylamine propionic acid, oxyethylene type collector.

Anionic collector is a collector that is adsorbed on the mineral surface after the dissociation of the active group of hydrophobic minerals. It is main type of tungsten scheelite collector. There are four catagories: fatty acid, sulfoacid, phosphoric acid and chelating agent.

Wolframite slime is an beneficiation issue due o its fine particle. It is ever harder to recycle finer minerals in slime. In recent years, to deal with fine particle wolframite slime effectively, there is a method to accumulate first and beneficiation second, selective flocculation flotation method is one of the newly developed wolframite slime recycle method.

Wolframite slime becomes beneficiation issue due to its fine particle. Recycle for finer minerals in slime is even harder. In recent years, to deal with fine concentrate slime effectively, there are other methods which accumulate first and beneficiate second. Carrier flotation method is one of the newly developed wolframite slime recycle method.

Tungsten concentrate is fragile mineral, during beneficiation process, wolframite slime can easily come into being, and will be neglected in tabling. There are still much tungsten element in slime. 

Tungsten scheelite flotation is difficult in separation of scheelite and gangue minerals. Calcium ion affects selectivity of collector. To improve selectivity, pH value regulator shall be added to create better flotation environment for scheelite flotation.

As we all know, tungsten scheelite deposit is very complex. Tungsten scheelite is in poor grade, there area associated ores as well, including copper, molybdenum, bismuth, tin, lead, zinc, tantalum, niobium and calcite, fluorite, apatite, mica which containing calcium. 

In flotation mineral slurry, activator distribution is important for flotation. Metal ion attached on the surface of mineral can improve its electric potential, ion collector and targeted mineral can function better.
