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, particle size recovery, air flow, pulp density, etc.) As a result, it is difficult to study the effects of any single factor in isolation, and compensation effects within the system can keep process changes from producing the expected effects (Klimpel, 1995). This makes it difficult to develop predictive models for froth flotation,

Pulp Density - an overview | ScienceDirect Topics

The maximum ‘pulp density’ is usually about 50% solids by weight; above that level small fluctuations in density will seriously affect separation. A coneshaped discharge of 20°–30° reduced angle usually produces optimum conditions for separation. Cyclone control is best obtained by optimising the feed density.
