processing scheelite for tungsten

Tungsten Processing | International Tungsten Industry …

Concentrates (Primary Tungsten Sources) Modern processing methods dissolve scheelite and wolframite concentrates by an alkaline pressure digestion, using either a soda or a concentrated NaOH solution. The sodium tungstate solution obtained is purified by precipitation and filtration, before it is converted into an ammonium tungstate solution.

Direct Pressure Alkaline Leaching of Scheelite Ores and …

The average global recovery rates for processing scheelite ores by physical methods are normally in the range 50 to 70%, and it is problematic to attain a minimum grade of 60% WO3 in the concentrates without penalizing further this yield. Direct hydrometallurgical processing of low-grade concentrates or medium- to high-grade ores may become an interesting global economic alternative as it ...

About Tungsten

Unlike most base and precious metals, Tungsten is largely not smelted to form metal due to its high melting point and is instead extracted from crushed ore using a series of chemical reactions. Due to the high-capital cost associated with the construction of a chemical processing plant to produce APT, the most commonly traded form of tungsten, most junior miners produce a tungsten concentrate.
