Effect of high intensity conditioning on aggregate size of

Apr 01, 2008· The corresponding effect of agitation speed on flotation recovery is shown in Fig.7. When the agitation speed in HIC with the high energy impeller increases from 700 to 2 000 r/min, the change in flotation recovery is negligible. A further increase in agitation speed to 2 500 r/min, however, causes a noticeable reduction in flotation recovery.

Flotation Machines Mineral Processing Machine

Flotation is the most widely used beneficiation method for fine materials, and almost all ores can be separated by flotation. Another important application is to reduce ash in fine coal and to remove fine pyrite from coal. The flotation machine is mechanical equipment for realizing the froth flotation process and separating target minerals from ore.

Intensification of fine apatite flotation with microbubble

Nov 01, 2020· 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.
