Intensification of fine apatite flotation with microbubble ...

2020-11-1 · Fig. 1 shows the experimental setup of the apatite flotation and the close-ups of the column parts. The flotation column, which is made of plexiglass, is 1.68 m in height and 0.08 m in diameter. Since the objective of this work is to intensify the flotation of fine apatite particles, the scale-up task is not concerned and therefore this small column is investigated for convenience.
