Development of a carrying-capacity model for column

2000-7-1 · The carrying capacity of a flotation system is a function of the total mass of particles that can be floated per unit volume of air, which is commonly referred to as the mineralized bubble density. The estimation of the mineralized bubble density requires the knowledge of the method by which the particles pack onto a bubble surface.

2007-5-1 · 3.. ConclusionsIn considering theoretical approach and flotation experiences from the micro-scale to industrial large size cells and columns, it was found that for typical superficial gas rates of J g = 1–2 cm/s, the optimal range for mean bubble diameter size at the pulp–froth interface level is d b = 1–1.5 mm, in order to maximize the bubble surface area flux S b = 50–100 s −1.
