During flotation process, collecting agent will change surface dewatering property of tungsten element, floating tungsten grains will attach to bubble. Salicylhydroxamic acid is common used hydroxamic acid collecting agent. Compared to oleic acid, it has stronger collecting capability.

During flotation process, collecting agent will change surface dewatering property of tungsten element, floating tungsten grains will attach to bubble. Since chelating collecting agent has better selectivity for metal, chelating agent gains wider application in tungsten concentrate flotation. 

Tungsten ore component are complex in China, useful mineral grains are fine, low grade mineral is easy to beneficiate. In early period, tungsten concentrate and scheelite mixed ore is difficult to select. Thus caused a lot of waste in resource and increase cost. Economy efficiency is low. With newly development tungsten ore GY chelating collecting agent putting into use, it solves this issue.

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.
