Figure 1: The flotation system includes many interrelated components, and changes in one area will produce compensating effects in other areas (Klimpel, 1995) Froth flotation is a good example of an engineering system, in that the various important parameters are highly inter-related, as shown in Figure 1.

REPORT ON FLOTATION PILOT PLANT DESIGN AND ARRANGEMENT D2.1 8 | 26 2. FLOTATION OF SULPHIDE ORES 2.1 FLOTATION TECHNOLOGY 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.

froth layer. Particles that are retained in the froth are recovered at the lip of the froth at the edge 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 and the recovery is sometimes assisted by mechanical paddles.

Froth floatation 1. Froth FloatationPresented By:Gulfam Hussain 2. Introduction Floatation is an extractive process where variousminerals can be selectively extracted. Flotation is a selective process and can be used toachieve specific separations from complex ores. For example, in poly-metal ores such as Pb-Zn-Cu, floatation allows separate extraction of Pb, Cuand Zn.

1.2.2.1.2.2.1 Froth Flotation. The froth flotation process is more than a century old and was developed over a long period of time [8]. It takes advantage of the surface chemistry of fine particlesif one particles surface is hydrophobic and another is hydrophilic, upon generation of air bubbles, the hydrophobic particles tend to attach to ...

Diagram of froth flotation cell. Numbered triangles show direction of stream flow. A mixture of ore and water called pulp [1] enters the cell from a conditioner, and flows to the bottom of the cell. Air [2] or nitrogen is passed down a vertical impeller where shearing forces break the air stream into small bubbles.

In mineral flotation, rheological problems have the efficient upgrading of low-grade and complex ores. Since pulp and froth rheology are deemed to play different roles in influencing the separation performance, in this paper, a brief review on pulp and froth rheology in flotation is provided, with an objective of developing a basic understanding of rheology in flotation.

Since several types of flotation circuits can generally be employed in conjunction with the various processes for the flotation of different classes of minerals, an outline of the standard circuits in common use is best given before the processes to which they are applicable are described. The flow sheets illustrating them are diagrammatic, but, in cases where the circuit includes two or more ...

Rheological investigation of flotation froth has been extended from measurement to the variables determining froth rheology. It has been found that flotation froth is non-Newtonian flow with pseudo-plastic nature, namely froth becomes less viscous at a higher shear rate, and vice versa (Li et al., 2015, Shi and Zheng, 2003).
