1. Introduction. It is well known that the bubble size distribution at the froth surface of flotation cells gives much valuable information regarding the process conditions (i.e. air flow rate, slurry level, pH, reagent dosage and slurry solids %) and performance (i.e. recovery and grade) [4].Hence, the flotation performance can be reasonably predicted …

Over recent years a number of techniques have been developed as part of the AMIRA 2 P9 project to represent mathematically or measure directly sub-processes occurring in flotation cells. These include the determination of: • a machine parameter (bubble surface area flux, S b); a froth parameter (froth recovery, R f); entrainment and …
