Flotation Developments & Best Practice International Mining
Flotation Developments & Best Practice. Posted by Daniel Gleeson on 4th November 2013. Prof Graeme Jameson is a nominee in the International Mining Technology Hall of Fame and his Jameson cell, marketed by Xstrata Technology, offers, among other advantages, high production in a small footprint and high concentrate grades.Abstract. It is clear that along with gas dispersion characteristics, the energy dissipated by the impeller is process determining in flotation, and its effect on flotation kinetics has been widely studied. However, turbulent conditions inside a flotation cell have usually only been changed by varying impeller speed or air flowrate or both.The effect of cell hydrodynamics on flotation performance
