Use washing to remove very fine harmful particles. Washing of run-of-mine ore can be carried out to facilitate sorting by removing obscuring dirt from the surfaces of the ore particles. However, washing to remove very fine material, or slimes, of little or no value, is more important. Washing is normally performed after primary crushing as the ...

The effect of the current is lessened as you go to the side or get farther away from this point, the current is much the same within the fine ore storage area. The difference here is the faster settling fine material is being pulled toward the exit first. This means that as the bin is emptied there will be less and less fine material in the feed.
