Wolframite slime becomes beneficiation issue due to its fine particle. Recycle for finer minerals in slime is even harder. In recent years, to deal with fine concentrate slime effectively, there are other methods which accumulate first and beneficiate second. Carrier flotation method is one of the newly developed wolframite slime recycle method.

Tungsten concentrate is fragile mineral, during beneficiation process, wolframite slime can easily come into being, and will be neglected in tabling. There are still much tungsten element in slime. According to statistics data, tungsten metal in wolframite slime accounts for 11~14% in original mine, even higher than it. To improve recovery rate of slime is important to achieve efficiency.

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.

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.

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. 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.
