Froth Flotation of Tungsten Ore
Scheelite (CaWO4) and Wolframite ((Fe,Mn)WO4) are the principal minerals of tungsten, but other important minerals include ferberite (FeWO4) and huebnerite (MnWO4) will also respond to froth flotation.The high specific gravity of these minerals makes many of these ores amenable to gravity concentration methods, however, the fine dissemination of mineral in gangue for some
Froth flotation of scheelite A review ScienceDirect
The classic way to go it the “lime flotation process” involving lime, sodium carbonate as a co-pH modifier, a fatty acid as a collector (usually sodium oleate) and sodium silicate as a depressant for the gangue. Scheelite flotation has run into serious difficulties when it requires separation of scheelite from a carbonaceous gangue.

Different Flotation Performance of Ultrafine Scheelite
In industrial practice, hydrodynamic cavitation (HC) is commonly triggered by jetting either reagent solution or pulp. Although both methods can enhance mineral flotation, are their roles the same? There are few research studies in the field, which severely limits our understanding on mineral flotation combined with HC. Therefore, in this study, the flotation of ultrafine scheelite with HC
