Mixing and Hydrodynamics in Flotation Cells | SpringerLink
The flotation process is a complex interaction between the physicochemical characte- ristics of the species involved and the hydrodynamic and operating conditions in flotation cells. Efficient cell design requires knowledge about the power to be provided and the time to be spent in the cell by each one of the phases.

Flotation Froth
Froth flotation is the most widely used separation process in modern paper mills. During the last 10 years, the development of flotation de-inking cells has been pursued more aggressively than the technologies of any other segment of the pulp and paper industry. Initially, Denver flotation cells used in the mineral industry were installed in ...
Jameson Cell fundamentals––a revised perspective
The Jameson Cell was a joint development between Mount Isa Mines and Prof. G.J. Jameson of the University of Newcastle, Australia ( Jameson, 1988 ). Since its invention in 1986 there have been 225 Jameson Cells installed in a variety of applications. Although the Jameson Cell is widely installed in the flotation industry there still remains …
Column flotation: A selected review, part II
The Jameson cell has a single orifice and uses a 2 to 4 m high vertical pipe (downcomer) to provide gas/slurry contacting prior to entry into the flotation cell. In the Jet Flotation cell there are five 1 mm diameter orifices and no downcomer; the slurry/gas mixture impinges on a plate within the cell. - The approach used by AFT flotation [37 ...
A Review of Flotation Physical Froth Flow Modifiers
Over the past few decades, the need to process more minerals while lowering capital costs has led to an increase in the size of flotation cells, e.g., 0.03 m3 to 1000 m3. However, this increase has created new challenges in the operation and design of industrial flotation cells, particularly in terms of froth removal, because the distance the …

Initially the flotation study was carried out using conventional reagents only in a Denver D-12 sub-aeration flotation cell. Then it was pre-treated with aliph. alcs. i.e., ethanol and butanol to de-oxidise the coal surface. The attempt was also made using a non-conventional reagent known as black oil as promoter for this type of coal to ...
SELECTION OF MECHANICAL FLOTATION EQUIPMENT
Modern flotation cell design is based on a cylindrical tank (Figure 2), and these are ommonly known as c Tank Cells. The cylindrical tank design allows for a more even flow pattern than the earlier 'hog-trough' style cells and consequentlythese units have better air and solids dispersion throughout the tank. Each tank can have their
