In accordance with the characteristics of the separation of coarse fine-grained wolframite, the process has been optimized by the process of "centrifugal enrichment throwing tail - sulphide flotation - magnetic separation iron removal - high gradient magnetic separation - shaking bed gravity separation - black tungsten flotation".
The separation methods have evolved from the froth flotation, magnetic separation and gravity roughing to hybrid or classified flotation flowsheet (Clemente et al., 1993). Thus, it is urgent to apply these methods so that more tungsten resource can be recovered from such tailings.
A large amount of collectors, inhibitors and modifiers such as oleic acid, water glass and sodium carbonate are added to the flotation processing of tungsten ore, resulting in the difficulty of the suspended solids (SS) with the residual water glass settling down in the flotation wastewater. The removal efficiency of the suspended solids is low with …
