Imhoflotpneumatic flotationtechnology has evolved through 25 years of industrial applications. This has led to the development of thepatented Imhoflot G-Cellwhere centrifugal forces are used in thecellto quickly separate the phases after mineral collection and therefore considerably reducing the size of vessels required. Imhoflot is characterised by:
Flotation columnscomprise a tall tank, in which the separation between froth and pulp occurs, anaerationsystem, a pulp level control system, a wash water system, a discharge barometric leg and a set of control instruments, besides pipe connections for feed, concentrate and tailings. Figure 1 illustrates a typical column. Figure 1.
Our RCS™ flotation machines are built with efficient air and level controls with controlled aeration rate at each cell. The pneumatically operated dart valves help in effective pulp level control followed by accurate measurement with ultrasonic level sensor and float.
Apneumatic flotation celloperates on the principles of mixing the air and pulp in a continuous stream, and ensuring that correctly sized bubbles are fed into thepulpas it enters thecell. This maximizes the number of particle and bubble collisions.
First, the collector is added to the iron ore slurry to selectively coat the iron oxide particles, making the surface hydrophobic. The slurry then goes to aflotation cell, where air bubbles are generated using an impeller and aerator (Figure 1.2.4). At this step, the frother (for example, fuel oil) is added to the ore slurry to form stable froth and air bubbles.

Theflotation cellsare designed for a variety of throughput requirements, ranging from small pilot sizedcellswith a diameter of 0.8m, processing 6 – 10 m 3 /h of feed; tocellswith a diameter of 6.5m, handling feeds of 1500 m 3 /h. Theflow rateis dependent on the feed pressure and rate of concentrate removal.
The design objectives for Imhoflotpneumatic flotationare to separate and optimize the independent process steps that make up frothflotation:aeration, bubble-particle contact and froth separation. Theaeratoris self-aspirating and uses a high shear ceramic multi-jet venturi system operating at around 2.5 bar (250 kPa ) back pressure.
Most of the industrialflotationmachines used in the coal industry are mechanical, conventionalcells. These machines consist of a series of agitated tanks (usually 4–8cells) through which fine coal slurry is passed. The agitators are used to ensure that larger particles are kept in suspension and to disperseairthat enters down through the rotating shaft assembly (Fig. 11.13).

Savona Equipment is aflotation cellsupplier worldwide. Frothflotationis a process for selectively separating hydrophobic materials from hydrophobic. This is used in several processing industries. Historically this was first used in the mining industry. Frothflotationimproved the recovery of valuable minerals, such as copper- and lead-bearing minerals.
