Wolframite

Wolframite, Fe,MnWO 4, is an iron manganese tungstate mineral that is the intermediate between ferberite Fe 2+ rich and hübnerite Mn 2+ rich. Along with scheelite, the wolframite series are the most important tungsten ore minerals. Wolframite is found in quartz veins and pegmatites associated with granitic intrusives.Associated minerals include cassiterite, scheelite, bismuth, quartz

Extraction of Tungsten from Scheelite Ore

The percentage of impurity in the original concentrate is generally so high that re treatment for their removal, generally by re flotation and acid treatment, is necessary. A marketable grade of scheelite is rarely, if ever, made by flotation, but an increased recovery is realized by its use and the product can be treated by soda ash solution in an autoclave.
