TUNGSTEN PROMETIA

TUNGSTEN Tungsten (W) is a lustrous greyish-white metal, which is a solid at room temperature. It has the highest melting point and lowest vapor pressure of all metals, and at temperatures over 1650ºC has the highest tensile strength. It has excellent corrosion resistance and is attacked only slightly by most mineral acids [11].

Decomposition Process of Wolframite in Mixed Symbiosis Ore

The wolframite was partially converted into scheelite. The tungsten ore was leached for 4 hours in a mixed acid solution with H 2 SO 4 concentration of 250g/L and H 3 PO 4 concentration of 300 g/L, and the liquid-solid ratio was 101 mL/g. The leaching rate of tungsten was 99.2%.

Tungsten Wikipedia

Tungsten is found mainly in the minerals wolframite (ironmanganese tungstate (Fe,Mn)WO 4, which is a solid solution of the two minerals ferberite FeWO 4, and hübnerite MnWO 4) and scheelite (calcium tungstate (CaWO 4). Other tungsten minerals range in their level of abundance from moderate to very rare, and have almost no economical value.

Abstract. Scheelite and scheelite-wolframite mixed concentrates with different grades were decomposed by caustic soda digestion, and the effects of caustic soda (NaOH) dosage, the ratio of water to ore and the stirring rate on tungsten recovery were studied. The results show that under the conditions that the ratio of water to ore is 0.8,
