How to Maximize Grade and Recovery High grade

It is clear that the flotation circuit 1 is out of the competition, nor the grade neither the recovery were maximized (100 microns was not enough for liberating that ore) Both flotation 2 and 3 gave higher grade and recovery In flotation 2, I got the max grade, while in flotation Keywords Iron Ore Flotation, Reverse Cationic Flotation, Reverse Anionic Flotation, Alumina Removal, Phosphorus Removal 1 Introduction With the depleting reserves of highgrade iron ore in the world, various beneficiation methods have been employed to process intermediate and lowgrade iron ore in an attempt to meet the rapidly growinghigh grade gold ore flotation cell concentration Figure 7 Graderecovery curve of the Gonçalo lepidolite froth flotation Similarly to what occurred with spodumene, it was not possible to obtain concentrates with Li 2 O grades close to the Gonçalo lepidolite Li 2 O content (558 % Li 2 O [31]), even after the cleaning stage, having been 450 % Li 2 O the maximum value achieved The shape of the graderecovery curve indicates that the IJMMME Flotation of lithium ores to obtain high
