1. Introduction. Froth flotation is a widely used separation process throughout the mineral processing industries in the last century because of its ability to treat complex and low grade ores, where the mineral particle size is too small for other separation techniques to be efficient.

The flotation tests were carried out using a 2 m high continuous column flotation cell which facilitated the generation of a deep froth, since this was the phase of most interest. The results were analysed using statistical analysis software that fitted a regression model to the data for each of the outputs.
described as a series of N continuous perfectly mixed reactors, where N corresponds to the actual number of cells in the bank. Keywords: residence time distribution, radioactive tracer, froth flotation, flotation machines, modelling.
Froth flotation is considered to be the most widely used method for ore beneficiation. In ore beneficiation, flotation is a process in which valuable minerals are separated from worthless material or other valuable minerals by inducing them to gather in and on the surface of a froth layer.

The most rapidly growing class of flotation machine is the column machine, which is, as its name implies, a vessel having a large height-to-diameter ratio (from 5 to 20) in contrast to mechanical cells.
FX Model Continuous Mechanical Flotation Machine is applicable to separation of minerals with float-free method in labs. It is a unit of several combinations of two cells with number of the cell being even, varying from two to ten cells.
The column flotation process has a substantial advantage over the mechanical batch flotation process for achieving higher grades with reduced maintenance cost as well as better control on the froth depth (Wheeler, 1985, Finch and Dobby, 1990, Sastri, 1998, Bhaskar Raju and Prabhakar, 2002).
The froth flotation process model was developed by drawing the analogy between a single flotation stage and a continuous stirred-tank reactor. Flotation kinetics were described by a model that is first order in displacement of solids concentration from equilibrium.
In the froth flotation of coal, especially coking coal, improved results are observed when using as a collector an oil distillate cut within the range 80/sup 0/ to 250/sup 0/ C., containing less than 20% by weight of naphthenes, less than 20% by weight of aromatic content and more than 60% by weight of n-alkanes and branched-alkanes.
of the flotation cell. The recovery of the froth is accomplished by the natural mobility of the froth which causes it to flow over the weir and the recovery is sometimes assisted by mechanical paddles. Within this general macroscopic view of the flotation process as a whole, several distinct micro

Abstract: Froth flotation is a widely used process of particle separation exploiting differences in surface properties. It is important to It is important to point out that overall flotation performance (grade and recovery) is a consequence of the quality and quantity of the solid particles
Froth zone: Zone in the top of the flotation cell consisting of froth loaded with mainly valuable minerals, which provides extra separation between valuable minerals and gangue minerals.

Conversely to the employment of mechanical agitation in conventional froth flotation for the aeration of a mineral pulp or slurry, column flotation uses an array of air spargers to introduce a fine upward rising air bubble distribution at the base of a column flotation cell.

Foam is a substance formed by trapping pockets of gas in a liquid or solid. A bath sponge and the head on a glass of beer are examples of foams. In most foams, the volume of gas is large, with thin films of liquid or solid separating the regions of gas. Soap foams are also known as suds. . Solid foams can be closed-cell or open-cell. In closed-cell foam, the gas forms discrete pockets, each ...
