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.
The flotation machine is used for mineral processing. The ore slurry is doped, stirred, aerated, and mineralized through a preprocessor so that some of the mineral particles are selectively fixed on the bubbles; they float to the surface of the slurry and are scraped out to form products. It is retained in the slurry […]
