Oxidized paraffin soap uses petroleum as raw material, obtained by oxidation and saponification treatment. Its appearance is brown red or yellow powder, soluble in water.

The whole process for producing tungsten wire is roasting APT to BTO, doped other elements when special properties are required, reducing the BTO to tungsten powder, pressing to blank tungsten bar, sintering, swaging, annealing, swaging, and drawing to tungsten wire.

Non-ionizing collector is a kind of auxiliary type of tungsten scheelite collector. Because it does not exist in its own solid group, it can not be formed on the surface of the mineral adsorption layer, and only physical attachment in some natural hydrophobic mineral surface, so such collector can only be used to capture graphite, molybdenum ore, sulfur and other natural floating minerals, can not be used alone to float scheelite.

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.

Wolframite slime is a beneficiation problem due to its fine grain size. In China, use flotation method to deal with wolframite slime is common method. At abroad, Maudsley tabling gravity separation method is used to realize wolframite slime recycle.

Tungsten concentrate is fragile mineral, it can easily form into slime during beneficiation process. So there is useful tungsten element in tungsten tailings. 

Tungsten concentrate coarse separation is gathering tungsten ore from mine, then enters the first premium grade separation process before gravity separation. 

Gravity separation is the main tungsten concentrate beneficiation method, coarse separation, gravity separation and selection are three steps. Jigging separation is one of the important processes of gravity separation. The recycled tungsten concentrate in jigging separation accounts for more than 50% of the whole separation process.

Gravity separation is the main tungsten concentrate beneficiation method, coarse separation, gravity separation and selection are three steps. Table separation is one of the important processes of tungsten concentrate gravity separation. It is the advanced processing for tungsten tailings from jigging.

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.
