Summary

Enhanced flotation cell: The generation of higher turbulence combined with adjusted air bubble size is a solution to floating fine particles. The innovation is an example for academic research that crossed the "innovation valley of death".

Description

The Jameson cell has been developed to improve fine particle flotation by intensifying the froth flotation process (i.e. high turbulence and small bubble sizes for increased particle bubble collision rate). Opposite to conventional cells, the air is entering the cell together with the pulp via a so-called down-comer, where fine bubble generation and intensive mixing takes place.

The innovation was initiated by an R&D project ordered by the mining company Mount Isa Mines from the inventor Jameson, a researcher at the University of Newcastle. The development was further supported by the company through financing pilot-scale testing and the ordering of initially two full-scale cells.

1986 Patent application
