— Removal of quartz from iron ore was accomplished industrially via an anionic reverse flotation technique However in that kind of flotation the interaction of the flotation reagents with the
— In the system with pyrite only the effluent pH sharply dropped to pH levels and then increased gradually as the total solution volume treated approached 4000 mL The initial decrease in solution pH was consistent with the pyrite oxidation Reactions 2 3 After 4000 mL the effluent pH exhibited much higher rise as consistent with the
