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,
