The Use of the Jameson Cell to Improve Flotation Circuit …
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.

Sampling from large flotation cells
The development and implementation of larger flotation cells has proceeded very fast. In a period of just 30 years of time, the cell size has increased from below 100 m3 to over 600 m3. Figure 1 depicts the size of flotation cells over time. Figure 1. Flotation cell size development throughout the years (Outotec, 2012)
Regular maintenance inspections help achieve optimal
Maintenance for flotation machines is often compromised because lack of resources and time to drain and clean the cells. On the other hand, flotation cell maintenance is not conducted in a timely manner because often site personnel are not sure what to look for when inspecting the equipment. Unless the problem is obvious, they are …
