The texture of particles within a flotation cell play a pivotal role in both mineral recovery and the grade in the flotation concentrate Theoretical curves can be generated based on particle mineralogy and texture to indicate the maximum graderecovery possible for a given feed ore
Improved froth handling and highconcentrate grade By containing the intense circulation energy at the bottom of the cell the upper zones of the cell remain quiescent or passive to maximise recovery of marginally attached coarse particles and minimise the carriage of undesired material
