The flotation collar has a fabric shell housing two automatically inflatable, independent, and symmetric flotation cells; two oral inflators and mechanical inflators mounted on the fabric shell; and a face shield stowed in the fabric shell.
The right amount of air, together with the optimized injector geometry lead to optimum bubble size distribution − the key to excellent deinking performance. Superior flow conditions inside the cell enable best results in dirt speck removal and increased brightness at lowest fiber loss.
no flotation can occur. Contact between particles and bubbles can be accomplished in a flotation cell such as the one shown schematically in Figure 5. Figure 5: Simplified schematic of a conventional flotation cell. The rotor draws slurry through the stator and expels it to the sides, creating a suction that draws air down the shaft of the stator.

Jan 01, 2002· Flotation is a difficult process to run efficiently. One way to make flotation performance better is to improve cell level control. However, controlling pulp levels in flotation cells is a complex control task because of strong interactions between the levels in flotation cells. Therefore advanced controllers are needed to give good level control.
Froth flotation is a selective process for separating minerals from gangue by using surfactants and wetting agents. The selective separation of the minerals makes processing complex (that is, mixed) ores economically feasible. The flotation process is used for the separation of a large range of sulfides, carbonates and oxides prior to further refinement.

on the top of the flotation cell rather than mixed with the pulp prior to flotation (DeLozier et al, 2005). Laboratory and pilot plant experiments have demonstrated improvements in the flotation process. It is suggested that mixing the surfactant into the pulp before flotation may cause surfactant to adsorb to the pulp fibers making them more
