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 ores may .

Scheelite - an overview | ScienceDirect Topics

There are four common tungsten bearing minerals: farberite (FeWO 4), hubnerite (MnO 4), wolframite (FeMnWO 4), and scheelite (CaWO 4). To begin the reduction process the ore is ground by ball milling and is usually digested to form tungstic acid (H 2 WO 4). A typical reaction for sheelite, one of the most common ores of tungsten, is
