Cationic collector is the active groups adsorbed on the mineral surface to make the mineral hydrophobic cationic after dissociation. It can be used as tungsten scheelite collector. Fatty amines collector is the main type.
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. According to statistics data, tungsten metal in wolframite slime accounts for 11~14% in original mine, even higher than it. To improve recovery rate of slime is important to achieve efficiency.
Tungsten concentrate after gravity separation still has high density minerals such as tinstone, scheelite, molybdenum and bismuth. Quality and purity can not meet standard. So tungsten concentrate selection is needed.
Tungsten concentrate rougher flotation is the first pre-selection process after it is explored form mine. Due to uneven distribution of tungsten concentrate in quartz vein mineral, waste ore will be blended during exploration process. Pre-selection of concentrate and waste ore will improve efficiency, save cost and time, lowering wastage.

Wolframite slime is a difficult issue of tungsten beneficiation due to its fine particle, recycle for fine minerals particle in slime is even more difficult. In recent years, to deal with fine wolframite slime more efficient, there are methods for gathering first and beneficiation second. Oil agglomeration method is a newly developed wolframite slime recycle process.
