Fatty acid flotation versus BHA flotation of tungsten

The similar flotability of scheelite, fluorite, and calcite resulted in the difficult separation by flotation. This work revealed the effect of water glass on the flotation of scheelite by FTIR and the wettability change of the usual cleavage plane, and proved that water glass inevitably influenced the flotation of tungsten minerals to a large extent in traditional fatty acid flotation process.

Scheelite flotation production line,Scheelite

Scheelite flotation production line Introduction Scheelite sorting method can re-election, magnetic separation, flotation. Different types and nature of the ore beneficiation methods and processes used are different. But based on scheelite good floatability, more due to the presence in the ore of a similar nature to their gangue minerals calcium, which led to the flotation of complexity.

A significant improvement of scheelite flotation efficiency

This research demonstrates an effective application of etidronic acid to improve the scheelite flotation efficiency and reduce the consumptions of energy and reagents. The cleaning recovery is significantly increased by 7%, and the cleaning cost is reduced by 17% accompanied with the efficient improvement of roughing grade from 1.22% to 1.68% compared with that in previous month.

Beneficiation studies of tungsten ores A review

Scheelite (CaWO 4) and wolframite ((Fe, Mn)WO 4) are the only tungsten minerals mined commercially and are mainly found in five types of deposits: skarn, vein/stockwork, porphyry, disseminated and stratabound.Gravity concentration and flotation are the beneficiation techniques most commonly applied to scheelite ore, and gravity and/or magnetic separation for wolframite ore.

Study on the activation mechanism of lead ions in

Micro-flotation tests were conducted on the pure mineral to investigate the effects of Pb(II) on wolframite floatability. As shown in Fig. 2, the wolframite floatability with solely BHA collector was low.A maximum recovery of approximately 26% was obtained at pH around 8.5 when adding 5.8 × 10 −4 mol/L (corresponding to 1.6 kg/ton) BHA, indicating that interaction of BHA with wolframite was
