Measurement of particle loading on bubbles in the flotation process / M. H. Moys in Minerals engineering, Vol. 23 N° 2 (Janvier 2010)

The paper focuses on direct measurement methods developed under the direction of Moys at the University of the Witwatersrand and by Seaman and co-workers at the JKMRC, Brisbane, Australia. Deficiencies in both designs are identified and a new design which deals with all these deficiencies is proposed. A hydrodynamic model for this version is developed and tested in a water-only environment, then tested on the copper flotation plant at El Teniente. It was found that the new design had successfully dealt with prior method deficiencies and provided a very precise (relative standard deviation equal to 0.72%) measurement of the loading on the bubbles in five tests.
