The future of flotation
The tendency is to "treat large tonnages, grind all the material finely and let the downstream separation processes sort it all out. However, this is generally very inefficient and is neither responsible nor viable during downtimes." Major equipment suppliers meet that demand by designing ever-bigger flotation cells.
