The use of high volume flotation cells has

Procedures for the automatic design of flotation networks

Generally, a conservative approach is used to design plants based on conventional flotation cells and, given the arrangement of the banks, the fine tuning of the overall metallurgical performance of an existing flowsheet is possible by rearranging the concentrate launders to add or exclude from selected banks the last flotation cell.
