Impact crusher is mine crush equipment with high efficiency, can be used in tungsten ore beneficiation.

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.

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.
