Tungsten, because of its high strength and high melting point occupies a prime position amongst metals. With depletion of high grade resources considerable R and D work is still being carried out in tungsten producing countries around the world for the processing of low grade and secondary resources. The paper gives a brief review of the hydrometallurgical processes developed to recover. In India, the work on extraction of tungsten from wolframite concentrate has been carried out by Gokhale and Bhat (). They have studied the parameters such as: the amount of sodium carbonate, temperature and retention time on the extent of reaction with ore/concentrate containing 65% WO3. Extraction of Tungsten from its ore? Apr 17 Can anyone describe the process of Tungsten being extracted from any of its ores After having written an account on the extraction of Sodium and titanium from their ores I can postulate what the equations for this extraction process would be so can anyone simply describe what goes on in the industrial extraction process of Tungsten from its ore. Concentrates. Marketable ore concentrates of scheelite and wolframite (hübnerite, ferberite) contain typically 65 – 70 % WO -grade concentrates having lower WO 3 concentrations are seldom on the market and if so, only for a lower price. In fully integrated companies lower grades (% WO 3) are often preferred, because upgrading to high concentrations is mostly combined with a lower.

  Tungsten from the purified leach solution was extracted by 10% Alamine and 10% isodecanol in kerosene. The loaded metal when stripped with NH 4 OH produced ammonium paratungstate (APT) solution which was crystallised to get the crystal of APT.   Before hydrometallurgical extraction, the tungsten concentrate (WO 3 > 50 wt%) collecting is need from ore by the primary ore beneficiation process, which includes crushing, ball grinding, gravity separation (mainly jigging and de-sliming), flotation, electric separation and magnetic separation (Yang et al., a).One example that illustrates the composition of Chinese tungsten concentrates.   In this paper, the conditions for the extraction of tungsten from scheelite concentrate with caustic soda in an autoclave is described, together with the method of recovering unconsumed caustic soda from crude sodium tungstate leach solution as it is industrially applied in China. 2. Materials and methods Experimental materials.   Extraction of tungsten has a different method, include gravity separation, magnetic separation, flotation process. It can only constant testing to determine the best way to the extraction of tungsten from its ore. 1 Description of tungsten ore.
