Pneumatic cell flotation

May 21, 2013 The Pneuflot pneumatic flotation cell mixes the air and pulp in a continuous stream and ensures that correctly sized bubbles are fed into the pulp as it enters the cell. This maximises the number of particle and bubble collisions. The system is able to produce a wide range of bubble sizes between 0 and 1 000 m, allowing the equipment to be

    Flotation Cell - an overview | ScienceDirect Topics

    Imhof et al. (2005) detailed the use of pneumatic flotation cells to treat a magnetic separation stream of a magnetite ore by reverse flotation to reduce the silica content of the concentrate to below 1.5%. From laboratory testing, they claimed that the pneumatic cells performed better than either conventional mechanical cells or column cells

The machine, which is illustrated in Fig. 44, consists of a trough or cell made of steel or wood, whichever is more convenient, through the bottom of which projects a series of air pipes fitted with circular

    A pneumatic flotation cell operates on the principles of mixing the air and pulp in a continuous stream, and ensuring that correctly sized bubbles are fed into the pulp as it enters the cell. This maximizes the number of particle and bubble collisions. There are no rotational parts as in agitator cells, and unlike column cells, no further air

    Pneumatic flotation does not follow the rules generally accepted for tank cell flotation. The concept for Imhoflot pneumatic flotation is simple. Take a liberated, correctly prepared, activated and conditioned mineral particle which is hydrophobic. To this particle attach a correctly sized bubble

    In the Hybrid Flotation technology, the slurry and the gas are mixed in the chambers of the Ejector before the mixture is injected into the flotation cell. In the pneumatic section, turbulent flows possessing a high kinetic energy are generated. These ensure the generation of small gas bubbles of a desired size

    The pneumatic cell has a great potential for quartz reverse flotation in the iron ore industry, with the possibility of reducing the flotation time and increasing the metallic recovery. One stage of pneumatic flotation can replace the rougher and scavenger stages of mechanical cells, with a strong decrease in the footprint and enhanced

    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

The air jet is used not only to provide aeration but also to suspend the particles and provide circulation. This usually means that an excessive amount of air must be used, and as a
