    A novel flotation scheme: selective flotation of tungsten

    Apr 20, 2017 An improved synchronous flotation of wolframite and scheelite using Pb–BHA complexes as the collector was designed to be applied in the flotation of tungsten minerals in Shizhuyuan (Fig. 9). The new process is different from the traditional flotation process which uses chelating collector and fatty acid in the following ways

    Study on the Activation of Scheelite and Wolframite by

    The activation of scheelite and wolframite by lead nitrate with benzohydroxamic acid (BHA) as collector was investigated by means of micro flotation test, zeta potential measurement, X-ray photoelectron spectroscopy (XPS) analyses and density functional theory (DFT) calculation. The flotation results confirmed that the addition of lead nitrate can markedly enhance the recovery of scheelite
