Sep 01, 1976 Sep 01, 1976 The air flow number in flotation machine scale-up. Int. J. Miner. Process., 3: 257--280. The flotation cell is quantified as a mixing device for one, two, and three phase systems using combinations of water, air, and solids. To do this, power consumption was measured as a function of impeller speed, rate of aeration, and solids concentration

Oct 09, 2015 How to Calculate the Size of Conditioning Tanks & Flotation Machines. If the time needed to condition and float a particular ore is known, the size of the conditioning tank and the number of flotation cells required can be calculated from Table 28Read More
Aug 01, 1987 Turbulence in flotation cells. Int. J. Miner. Process., 21: 1-23. It is known that turbulence plays an important part in the operation of a flotation cell. Rota- tional speed and thus intensity of turbulence has a strong influence on the recovery and grade of concentrate of single cells and cell banks. In this investigation an expression forRead More
Effect of Cell Size and Number Consider a bank of 6 cells replaced by a single large cell of the same total residence time For 6 cells, recovery = 94% For a single large cell (same total volume), = 6 x 2 = 12 min Recovery = 1 – -(1+0.3 x 12)1 = 78% The difference in recovery is the result ofRead More
Self-aspirated or poorly performing forced-air flotation cells can present a number of challenges, such as the process stability, the sanding and “wave effect”. Typical self-aspired cell challenges. As cell volume increases, constant and evenly distributed air becomes an issue to the process environmentRead More
Constraints on the size (V) and number (N) of flotation cells. These constraints can be added to the general formulation according to the available cell sizes in the industry and typical number of cells in an individual flotation bank. Based on these observations, the following constraints are imposed:Read More
Figure 6 shows the relationship between the flotation volume and power number or power intensity. For flotation cell volume ranging from 70 to 680 m 3, the power number remines at about 5.4, illustrating a good balance between the volume and power during the cell scale-up. Generally, the power intensity decreases as the volume increasesRead More
The Peclet number is a function of gas and liquid velocities (Vg,l), column height to diameter ratio (L:D) and air hold-up. It has been shown that the Peclet number for a column flotation cell can be described as follows (Mankosa et al, 1992):  Both column and conventional flotation cells operateRead More

Froth flotation processes are carried out in flotation cells that are grouped into banks, and these banks are interconnected, forming a flotation circuit. A literature review shows the existence of papers related to flotation circuit design based on mathematical programming. However, due to the complexity of solving the mathematical model in most of the work, it is considered that a smallRead More
cells and details of this design will be discussed later in this article. The top section of the disc connects to a drive shaft which in turn connects to the pulley/gear-motor drive assembly. The impeller is located in the centre of the cell cross-section with its II/FLOTATION/Flotation Cell Design: Application of Fundamental Principles 1505Read More
The MAC flotation cell is mainly used in the flotation section of waste paper deinking pulping, for removal of hydrophobic impurities such as filler, ash, ink particles, etc. It can increase pulp whiteness and meet the requirements of final paper appearance quality. Table 11.11 shows the features of MAC flotation cellRead More
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 statorRead More
flotation cells, of large size, can deviate significantly from perfect mixing, while in terms of process modelling the mixing conditions in a flotation bank of mechanical cells (3, 5 or 7 cells in series) can be well described as a series of N continuous perfectly mixed reactors, where N corresponds to the actual number of cells in the bankRead More
