عرض المزيدINTRODUCTION TO 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 intense mixing and fine bubbles.
عرض المزيدThe flotation equipment with a downcomer such as the Jameson Cell has proven a significantly reduced residence time compared to conventional flotation cells (Harbort et al., 2003a). This design also increases the throughput through a reduced residence time while maintaining a small footprint ( Lawson, 2016 ).

عرض المزيدThe accolades are an acknowledgement of Jameson's groundbreaking flotation technology, the Jameson Cell. The technology, which was made available in the late 1980s after 20 years of research, enables the mining industry to create billions of dollars of extra value by using bubbles to capture super-fine particles of less than a …
عرض المزيدThe 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.
