Brief Description
Description : | The technology will be useful for the production of tungsten metal powder from industrial waste with low tungsten concentration/lean grade ores.Based on the characterization, laboratory, and pilot-scale studies technology was developed for the production of tungsten metal powder from plant tailings/rejects with an extremely low concentration of tungsten (0.02 WO3). The important technical features are the followings: A novel route for beneficiating extremely fine-grained and low tungsten assaying plant tailings/waste material to a product suitable for the extraction of tungsten. Hydrometallurgical extraction of tungsten from pre-concentrate involving alkali leaching, solvent extraction crystallization of ammonia para-tungstate (APT). Production of high purity (99.9%) tungsten metal powder from a high-temperature reduction of APT. |
