Flotation stabilization and optimization - SAIMM

2009-8-26  Flotation stabilization and optimization by A. Singh, J.J. Louw, and D.G. Hulbert* Synopsis The control of flotation plants is by no means trivial. Flotation is one of the most interactive minerals’ processing operations. The interactive nature of flotation circuits results in oscillations of levels and hence of grades and recoveries.
