Effect Of Primary Grind Size On Mineral Liberation. The extrapolated ore fragmentation and copper sulphide liberation plots reveal that the liberation levels and hence the flotation responses of the minerals would be essentially constant across a broad range of flotation feed sizing This observation would indicate that flotation feed sizing coarser than 200µm K80 …
The Effect of Grinding Media on Mineral Breakage ...
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 …
