Section snippets Modelling of degree of entrainment. Two empirical models for degree of entrainment available are tested: Bisshop and White (1976): ENT i = 1 + α · τ fw 1 + β i · τ fw α = k 1 · (ρ m-ρ p) β i = α · exp (k 2 · d i) where α and β i are the drainage parameters of water and entrained particles, respectively, τ fw is the froth residence time …

The scale-up relationship was developed based on dimensionless parameters. First, a scale-up factor (ξ) was defined as the ratio between the actual flotation rate (k AC) of the collection zone in a perfectly mixed industrial cell (N = 1) and the flotation rate (k B) in a laboratory batch cell, (1) ξ = k AC k B The apparent flotation …

Flotation in the mining industry is a very significant separation technique. It is known that fine and ultra-fine particles are difficult to float, leading to losses of valuable minerals, mainly due to their low collision efficiency with bubbles. Flotation of fine particles can be enhanced either by increasing the apparent particle size or by decreasing the …

Bastnaesite is an important strategic resource. Since the calcium-bearing gangue minerals in the pulp can dissolve and release Ca 2+ ions, Ca 2+ ions and sodium silicate have a co-depression effect on bastnaesite flotation, which will affect the separation and purification of bastnaesite. In this study, the mechanism of eliminating the co …

Entrainment is a mechanical transfer process that operates parallel to flotation, by which the mineral particles that are suspended in the air-bubble water enter the froth layer and are transferred out of the flotation cell [7,8]. It has a detrimental effect on the flotation separation of valuable minerals from large amounts of fine gangue [6,9].
