Bubble surface area flux.The collection of mineral particles by bubbles greatly depends on the amount of bubble surface available. Therefore, a more adequate way of tracking the influence of gas to the flotation process is to use the amount of bubble surface per unit time and unit of column cross sectional area instead of the gas hold-up. This …

The effect of R f on the overall recovery R is clearly significant (Eq. (1)).A particle may be collected in the pulp zone and report to the froth zone. However, if the recovery in the froth zone R f is low then the particle would most likely not be recovered into the concentrate but would drop back to the pulp. To illustrate the effect of R f on R, a 3D …
