ABSTRACT:
In a flotation system, the generated quantity of foam is determined and, independent thereof, process parameters which directly or indirectly affect the generated foam quantity are reduced in their quantity depending on foam quantity. This is brought about by reduction of specific substance flows and also such substance flows that circulate in a flotation system. Production waters used for dilution are partly replaced by fresh water. This precludes an excessive amount of generated foam from causing difficulties in the operation of a flotation system.
