Design of Flotation Cells and Circuits
Circuit Design and Operation. The accelerating trend to larger flotation cells will be considered in these aspects: picking the right equipment and putting it together in the right manner. The first problem we run into in choosing the right machine is the scale-up from the laboratory or pilot-plant test results to full scale, and this is a ...
