Trends with Selection and Sizing of Large Flotation

Flotation response = particle characteristic x cell characteristic k = P S B R F where P = a parameter related to ore floatability S B = the bubble surface area flux (=6J G /d 32) R F = a froth recovery factor The bubble surface area flux is defined as the total surface area of bubbles available in the cell per unit cross-sectional area of cell per

Calculate Flotation Cell Capacities Volume vs Retention Time

Five minutes conditioning time and 15 minutes flotation time are desired. Adding 15% as a volume factor for aeration, the estimated flotation cell volume needed will be 290 cubic meters. If cells of 29,000 Liters volume are chosen, N will be 10. Similarly calculating for the 5-minute conditioning time at the same pulp density gives (see below).

Design and Sizing of a Dissolved Air Flotation Separator

In general, DAF separators are sized by the flow rate verses the separation chamber's effective surface area (or projected surface area in the case of a DAF with enhanced "coalescing" or parallel plate media). Therefore, the effectiveness of any DAF separator is affected by the flow rate.

Forced-air flotation cell FLSmidth

Flotation is about creating the proper energy dissipation rate in the cells to obtain optimal contact between the air bubbles and the particles for extracting the minerals. The function of the rotor/stator is to make bubbles from the forced air, suspend the particles, and create an environment for bubbles and particles to make contact and rise to the top as froth for concentration and collection.
