The quantum change in Flotation cell design was the move to very large cells, with the development of large cylindrical cells by Outokumpu in the early 80s, with corresponding reductions in overall capital and operating costs, as well as ease of control. With developments in rotor and stator design, cells of up to 300 m3 are now standard, with plans for 500 m3 cells at full pilot scale.
In concluding Prof. Nelson mused on where the next innovations might be made and suggested that we should be looking outside the narrow confines of the minerals industry, and evaluate the methodologies used in related fields, such as dissolved air flotation in water treatment, and techniques used in oil and tar sands processing, as well as the new field of nanotechnology.
Overall I found this a very interesting and informative lecture, which was very well presented. Prof. Nelson has presented this before in various cities, so if it comes to an area near you, I would definitely advise that you make the effort to attend.
