A Brief Review of Pulp and Froth Rheology in Mineral Flotation. In most flotation pulps, a low solid concentration is generally used. The more dilute the pulp, the cleaner the separation .As can be seen in Figure 3, when the UG2 and Great Dyke feed solid concentration exceeds 25 vol.,a discernible increase in the apparent viscosity of the feed samples could be detected, which would result

1 Froth Flotation Fundamental Principles

2009-8-27  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. It is therefore important to take all of these factors into account in froth flotation operations. Changes in the settings of one factor (such as feed rate) will automatically cause or demand changes in other parts of the system (such as flotation rate,

Froth Flotation an overview ScienceDirect Topics

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 particles—if one particle’s surface is hydrophobic and another is hydrophilic, upon generation of air bubbles, the hydrophobic particles tend to attach to the air bubbles and float, allowing for a separation between particles in the froth and those in the main body
