The Effect of Grinding Media on Mineral Breakage ...

2021-12-11 · The breakage and liberation of minerals are the key to fluidized mining for minerals. In the ball milling process, steel balls function as not only a grinding action implementer but also energy carrier to determine the breakage behavior of ores and the production capacity of the mill. When ground products present a much coarse or much fine particle size distribution, the

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
