TL;DR: In this paper, an analysis on how the characteristics of flotation processes, the quality of measurements of key variables, and the general lack of realistic dynamic models, are delaying the appropriate use of predictive control is presented.

TL;DR: A survey of the control approaches for ore size reduction and mineral separation processes is presented in this article, mainly for grinding and flotation processes, and classified as mature, active or emerging.

TL;DR: In this article, the mixing characteristics of large-size industrial flotation equipment, consisting of banks of mechanical cells and pneumatic columns, have been observed using non-invasive experimental techniques, such as a radioactive tracer to measure the residence time distribution of the liquid and solid.

TL;DR: A review of the trends and state of art in automation and control of flotation columns is presented and it is expected that intelligent techniques will be incorporated to solve a large variety of problems.

TL;DR: The optimisation of flotation column operation relies mostly on the identification of the key variables to be controlled, how accurately they can be measured, and how coordinately their influence can be dynamically influenced as mentioned in this paper.
