Rougher Flotation Banks

A flotation bank is a serial arrangement of cells How to optimally operate a bank remains a challenge This article reviews three reported strategies air profiling mass pull froth velocity profiling and Peak Air Recovery PAR profiling These are all ways of manipulating the recovery profile down a bank which may be the property being exploited.
