3 Separation Methods for Wolframite Concentrating Mining

After classfying the coarse concentrate from shaking table, the -2 ~ 0.18mm particle size will be first processed with table flotation to get bismuth, then get sulfur and arsenic. Then use magnetic separation of table flotation concentrate to make wolframite, scheelite and bismuth oxide ore separated to obtain the final wolframite concentrate.

Tungsten Ore Extraction Processing Wolframite

Wolframite mineral processing method mainly in gravity separation, and includes four parts: pre-selection, gravity separation, concentration and recovery. By pre-selection and discarding the waste rock which accounts for 50% of the raw ore, the WO3 grade of the ore is enriched from 0.25% ~ 0.3% to 0.45% ~ 0.8 %, and the recovery is 96% ~ 98 %.

Wolframite Wikipedia

Wolframite, (Fe,Mn)WO 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
