Flotation Circuit - an overview ScienceDirect Topics

In this work, a new methodology that integrates the first five design steps outlined previously is presented. The objectives are 1) to better orient the goals of the laboratory tests; 2) to reduce the number of laboratory and pilot-plant testing, and achieving lower cost and execution times; 3) to design the flotation circuit systematically, and 4) to expedite the design process.

Flotation Process - an overview ScienceDirect Topics

Flotation processes are based on the different surface wettability properties of materials (Wang et al., 2015). In principle, flotation works very similarly to a sink and float process, where the density characteristics of the materials, with respect to that of the medium where they are placed are at the base of the separation.

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, although work is being done to develop simple models that can predict the performance of the circuit
