Sulfidation Process During Flotation

Selective Flotation of Chalcopyrite and Marmatite by MBT .

Selective Flotation of Chalcopyrite and Marmatite by MBT .

Various collectors were compared in the selective flotation of copper–zinc ore by using isopropyl ethylthionocarbamate (Z-200), buthl xanthate, ammonium dibutyl dithiophosphate, and mercapto benzothiazole (MBT). The latter showed effective selectivity in the flotation of chalcopyrite and marmatite and was selected for a detailed study by using cyclic voltammetry and Tafel.
