Effect of Grinding Media on Galena Flotation | SpringerLink

Grinding with steel media adversely affects the flotation response of galena. Electrochemical measurements, flotation tests, and examinations were employed to identify interactions between galena and mild steel. Iron oxide, hydroxide, or sulfate species that formed on the galena surface upon contact with mild steel decreased its floatability, with the time of contact and aeration …
