High Purity Tungsten Spherical Particle Preparation From WC-Co Spent Hard Scrap

High Purity Tungsten Spherical Particle Preparation From WC-Co Spent Hard Scrap

Tungsten carbide-cobalt hard metal scrap was recycled to obtain high purity spherical tungsten powder by a combined hydrometallurgy and physical metallurgy pathway. Selective leaching of tungsten element from hard metal scrap occurs at solid / liquid interface and therefore enlargement of effective...
