  • The Effect of Conditioning on the Flotation of Pyrrhotite

    The influence of conditioning on the flotation of pyrrhotite in the presence of chlorite was investigated through flotation tests sedimentation tests and X-ray photoelectron spectroscopy (XPS) analysis. The flotation results show that chlorite slimes dramatically impair the flotation of pyrrhotite. Sedimentation and flotation tests reveal that conditioning can effectively remove chlorite
