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.

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.

The AIM-listed firm said a potential second lode has been identified 20 metres to the north of the existing Desert Scheelite lode, while a 28 metre wide zone of copper, zinc and tungsten mineralisation was intersected near the surface at the Good Hope prospect.

EU Directive 2011/65/EU (RoHS 2) regulates the use of certain hazardous substances in electrical and electronic equipment. Lead, which is often used as radiation shielding or for anti-scatter grids, is ranked at the top of the list, even higher than mercury and cadmium. 

The price of one of the most critical materials for the Western world's economy and defenses is spiking faster than any other major commodity.

Tungsten concentrate coarse separation is gathering tungsten ore from mine, then enters the first premium grade separation process before gravity separation. Due to uneven distribution of tungsten concentrate in quartz vein mines, tailings mixed in the gathering process is huge. Separate tungsten concentrate and tailings at primary stage can promote efficiency of subsequent processes, save cost, time and lower wastage.

Flotation column is a new type of tungsten scheelite flotation equipment, it has a simple structure, small footprint, low cost, high degree of automation, low infrastructure investment, good flotation index and many other advantages, and gradually become mainstream in tungsten ore flotation.
