Tungsten Metallurgy

The grading, analysis, and marketing of tungsten ore is based on the tungsten trioxide (WO3) content and not on the metal content. Scheelite, the principle ore, for example, when pure, assays 80.6% WO3, and wolframite, 67.3 %WO3. Deposits are usually placers or fissure veins; less commonly it occurs in pegmatites and in contact metamorphic zones.

In this paper, beneficiation studies were carried out on a low-grade tungsten-bearing scheelite from Nezam Abad ore with total WO3 grade of 0.11%. Mineralogical studies showed that scheelite is mainly distributed in the ore and gangue minerals include Quartz and Tourmaline. Liberation degree (d80) of tungsten- bearing scheelite is achieved around particles size 150 μm.

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 …

Cassiterite Flotation

The nominal size range for cassiterite flotation is between 2 and 100 microns. The top size is variable depending upon the liberation of the cassiterite particles. Cassiterite grains coarser than 100 microns are difficult to float whilst grains finer than 2 microns give selectivity problems. Hence the feed for cassiterite flotation should be reduced to 95% minus 100 microns and then deslimed ...
