This is a situation pertinent to flotation but one difficult to explore experimentally. Thus, using the same approach aforementioned, the effect of bubble loading upon gas holdup and bubble size was addressed theoretically (Yianatos, J.B., 1988a).

5. The Contact Time And Time Flotation

This induction time is effected by the fluid viscosity, particle and bubble size and the forces between the particle and bubbles.In a typical pyritic gold ore, gold formulated in a crystal structure of iron sulfide. Highly oxidized ores generally do not respond well to flotation.

Changes in flotation rate were due to both changes in the coal particle size, and to frother/ collector dosage.It can be carried into the froth by attachment to an air bubble (true flotation), or it can be suspended in the water trapped between the bubbles (entrainment).
