pilot plant feed (scavenger concentrate) is approximately
20 µm. Figure 3 indicates the coarser particles floated faster,
particle size in concentrate of cell 1 (conc 1) is coarser than

Figure 4 displays the very small bubbles produced by
the pneumatic Imhoflot aerator, one of the main key fac-
tors in improving the collision efficiency between bubbles
and fine particles. Note that the bubble sizes in the pulp or
