Froth Flotation of Chalcopyrite/Pyrite Ore: A Critical Review
Pyrite and galena flotation with KEX had recoveries greater than 90% for each mineral (pH = 8). After adding chitosan (0.67 mg/L), the pyrite recovery decreased to 23% (pH 4−9). In a flotation with mixtures of pyrite and galena, the recovery of galena was much higher than separately, concluding that chitosan is preferentially adsorbed on pyrite.
