Modelling for froth flotation control: A review - ScienceDirect

Simplifications and combination of micro-scale models form the basis of macro-scale models, which have been used for the prediction of the behaviour of entire flotation cells – or even banks– the description of process parameters using experimental data, the design of plant layout, and the development of control strategies (Polat and Chander, 2000, Rojas and Cipriano, 2011, Jovanović et al., 2015). Given the massive difference in scale between models for those for an entire cell or ...

Design of optimal flotation circuits — a review

In this review article, various approaches and mathematical models that have been used to simulate, design, and synthesize flotation circuits are examined. First, a brief review of flotation kinetics is presented which is followed by a discussion on simulation of flotation circuits. The existing literature on optimal design of flotation circuits has been divided into two broad categories. In ...

Flotation Plant Controller - Metso Outotec

Our Flotation PlantController provides reliable and stable control over the flotation circuit, including air feeds, levels, and motors. It is an ideal platform for basic controls that can be easily connected to other systems like plant-wide SCADA or DCS, and the highly flexible system structure means it can be applied to all modern flotation ...

[PDF] Level control strategies for flotation cells | Semantic ...

Flotation is a difficult process to run efficiently. One way to make flotation performance better is to improve cell level control. However, controlling pulp levels in flotation cells is a complex control task because of strong interactions between the levels in flotation cells. Therefore advanced controllers are needed to give good level control. This paper deals with a model of six flotation ...
