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.

During flotation process, collecting agent will change hydrophobicity of tungsten element surface, floating tungsten ore grain will be attached on the foam. Oleic acid is common used tungsten beneficiation collecting agent both for concentrate and scheelite.

Industrial xanthate is not yellow medicine in herb, it is also called yellow catching agent due to its yellow appearance. It is the most widely applied desulfurizing agent in tungsten beneficiation process. Its main function is to catch sulfur minerals in tungsten ore and separate them.

In the process of tungsten ore beneficiation, sodium silicate is often used as inhibitor. However, sodium silicate can not solve all the problems. So there is also organic inhibitor in tungsten ore beneficiation.

Sodium silicate is glass cement. In tungsten ore beneficiation process, it is used as inhibitor. It belongs to inorganic inhibitor.

During flotation process, collecting agent can change hydrophobicity of tungsten element surface, floating tungsten ore grains will attach to foam. Tungsten concentrate flotation is mainly flotation of tungsten slime. 

Tungsten ore is fragile, during beneficiation process, tungsten slime is easily formed. So tungsten tailings still contain many effective tungsten metal elements.

Tungsten ore is fragile, during beneficiation process, tungsten slime is easily formed. So tungsten tailings still contain many effective tungsten metal elements. According to statistics, tungsten metal in slime usually accounts for 11%~14% of original ore.
