Recovery of Tungsten from Downstream Mineral Processing Fractions by Deep Eutectic Solvents

Materials Proceedings, 2022
Tungsten is a scarce and valuable metal with a wide range of applications. Currently, the recovery of tungsten from scheelite concentrates involves the use of strong acids, alkalis, and/or high temperatures (roasting).
