(COF) and the coarser and denser particles reporting to the cyclone underflow (CUF) for further grinding. Eventually, the ore is ground fine enough (typically in the range of 75-250 µm P 80) and reports to the cyclone overflow. From there, the fine gold particles that have reported to the cyclone overflow, are
The waste rock is mixed in during mining to dilute the ore. For this kind of ore, only crushing and no-grinding can be used so coarse-grained tailings are discarded through re-election to recover the geological grade. The other one is fine-grain gravity separation, which mostly deals with the hematite with finer grain size and high magnetic ...
If fine grit grinding wheels are used, makes the abrasives lose cutting effect, and makes the workpiece surface not finish. It is shown that F36, the F46 grain size is for rough grinding and F60 is for finish grinding. For both rough and finish grinding, F46 and F60 grain size grinding wheels are used.
The ball mill is the fine grinding machine connect the SAG or AG mill and flotation machine. Ball mills produce fine particles with a uniform size for flotation, its grinding medias commonly are steel ball. The ball mill rolls grinding media together with the ore, as the ore grinds, these balls initially 5-10 cm in diameter but gradually wear out.

Even though many ores require fine grinding for maximum recovery, most ores liberate a large percentage of the minerals during the first pass through the grinding unit. Thus, if the free minerals can be immediately removed from the ball mill classifier circuit, there is little chance for overgrinding.
