Celanese - The chemistry inside innovation

Flotation – A flotation frother – like Methyl Isobutyl Carbinol, 2-Ethyl Hexanol, or terpenic oil – and a "slurry" of fine powder and water are then introduced to a water bath (i.e., flotation cell) which is aerated, creating bubbles. Frothing – A stable froth is formed on the surface of the flotation cell from the aeration.

1 Froth Flotation – Fundamental Principles

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.

A froth flotation cell consists typically of a collection zone (or pulp zone) located below the feed particle point, and a cleaning zone, (or froth zone), above the particle feed point [26] (Figure 2). The collection zone is fed back-stream by the pulp pushed by the bubble swarm created by a gas sparger at the bottom of the flotation cell.

Different dosages of kerosene (70/210/350 g t −1) and MIBC (21/42/63 g t −1) were added to the 2.5 L flotation cell. The conditioning time was again 1 min for kerosene and MIBC and separate froth products were collected as flotation time elapsed (0.5/1.5/2.5/4.5 min). The impeller speed was 1200 rpm for both conditioning and froth collection.

US4247391A - Froth flotation cell and method of operation ...

Coarse particles of up to 3 mm are floated in a cylindrical froth flotation cell in which the agitation impeller has a cover preventing fluid from being drawn in above. Air is supplied from a ring around the periphery of the cell and situated above the cover. Baffles project radially inwardly up to a short distance from the top. Froth is allowed to overflow around the periphery of the cell.

Figure 5 from Level control strategies for flotation cells ...

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.

FLOTATION

In these equations, c is the solids concentration, c 0 is the solids concentration in the feed, and is the mean retention time of the suspension. Comparing the above equations shows that theoretically a plug flow flotation cell is more efficient than a perfectly mixed system (for the same k and ); to put this another way, a smaller plug flow tank will give the same recovery as a …

A Brief Review of Pulp and Froth Rheology in Mineral Flotation

For non-Newtonian flotation pulps, rheology is strongly dependent on the shear rate in a flotation cell [41, 42]. In several studies on pulp viscosity measurement (e.g., [19, 39, 43, 44]), apparent viscosity was obtained at 100 s −1 or 160 s −1 which are claimed to represent a typical shear rate in a mechanical flotation cell [19, 45].
