The Jameson Cell consistently produces fine bubbles and intense mixing between air and slurry. This means fast, efficient flotation. While the principle of using air bubbles to recover particles is the basis of the technology, it is the way air bubbles are generated and how the bubbles and particles interact that make Jameson Cells unique.

The Jameson Cell The Jameson Cell is a high intensity flotation cell in which pulp and air are brought together in a co-current descending flow in a vertical tube called the downcomer. The pulp is introduced into the downcomer through a slurry lens orifice to produce a high velocity jet that generates violent mixing and fine bubble size.

Introduction. Three distinct zones can be identified within a mechanical flotation cell: the turbulent, quiescent and froth zones. It is known that the highly turbulent zone is responsible for the key sub-processes (Schubert and Bischofberger, 1978, Schubert and Bischofberger, 1979, Schubert et al., 1982, Schubert, 1985, Schubert, 1986, …
