| Abstract Scope |
Wolframite ore, an industrial isomorphic mineral with varied Fe, Mn, and Pb ratios is useful in catalytic applications due to its astonishing properties including high melting points, hardness, excellent corrosion resistance, and thermal conductivity over other compounds. Consequently, the ore sourced from Anka, Zamfara State (Nigeria) was employed in studying the catalytic/oxidant properties using hydrometallurgical routes. The effects of process parameters such as reaction temperature, concentration, and particle size were investigated to obtain optimal extraction conditions for industrial tungsten compound. At optimal leaching (3M NaOH+0.15M H3PO4, 75°C, -90+75µm), 94.7% of the ore reacted within 120 minutes. The purification of the leachate by 0.25M Aliquat-336 yielded 96.7% pure tungsten, and was beneficiated to obtain high-grade Sodium Tungstate (Na2WO4.H2O : 96-901-3322, melting point: 703.4°C/698.1°C industrial standard). The product as characterized is recommended for use as a catalytic oxidant for defined industrial processes such as corrosion inhibitors in steel and high-tech applications. |
