1 Froth Flotation – Fundamental Principles
1 Froth Flotation – Fundamental Principles. Froth flotation is a highly versatile method for physically separating particles based on differences in the ability of air bubbles to selectively adhere to specific mineral surfaces in a mineral/water slurry. The particles with attached air bubbles are then carried to the surface and removed, while ...
Advanced Techniques on Fine and Coarse Particle Flotation
Flotation is a method that enables the separation of hydrophobic particles with the help of air bubbles (Fig. 3 a). In flotation, the particles adhere to air bubbles depending on solid, liquid, and gas contact phases. The interaction of particles and bubbles includes collision, adhesion, and stability [ 3, 4, 5 ].

Flotation circuits for poorly floating coals
Miner. Process., 5: 321--334. A number of flotation circuits for the recovery of a poorly floating coal were investi- gated by laboratory batch testing. Analysis of the size and ash distributions of the pro- ducts and tailings showed that the circuits which would allow an equitable distribution of collector between the coarse and fine size ...
Machine vision based monitoring and analysis of a coal column flotation
The literature on the use of machine vision in monitoring and control of coal flotation systems in particular in industrial-scale is sparse. Nguyen and Thornton (1995) used the froth textural features to identify a variety of froth classes in a coal flotation circuit [10]. They showed that there were correlations between the froth textural ...

The flotation circuit consists of a single flotation cell with 16 downcomers. It is to be noted that there may be a large variation in the yield of coal from the flotation circuit due to the numerous seams treated. However, the ash produced upon combustion of the flotation coal product is about 10% of the coal weight.

The Importance of pH in Flotation
To have a positive control over flotation, it is necessary to be able to determine which and to what degree it is. A cheap way to take this measurement, LITMUS PAPER or a pH METER is used. This is a very important measurement for the flotation operator. Some minerals like Iron pyrite will not float well in an alkaline flotation circuit.
