Tungsten is an element of the wider distribution of almost all kinds of rocks found all over.Tungsten ore low must be integrated mineral-rich concentrate to a smelting raw material. According to the type of tungsten ore dressing it can be divided into wolframite and scheelite mineral beneficiation two types.
Tungsten is recovered from scheelite ore concentrates, or other tungsten concentrates which may, or may not contain scheelite in the form of sodium tungstate and in yields up to 99.5 percent or more by a process in which ground ore substantially below 200 mesh in particle size is first added to a 50 percent sodium hydroxide solution while being agitated to such an extent that the resulting mixture becomes a semi-solid as the temperature is raised above 80C. The semi-solid is then baked at 135 to 145C for about 1 to 2 hours, followed by adding sufficient water to the semi-solid to form a slurry having a sodium hydroxide concentration below 6 molar, separating the causticinsoluble sludge from the slurry and washing the sludge with a dilute sodium hydroxide solution to remove residual sodium tungstate.
