Column flotation cells, like mechanical cells, are used to perform mineral separations. Column cells do not use mechanical agitation (impellers). Instead, mixing is achieved by the turbulence provided by the rising bubbles. Columns are mostly used to produce final grade concentrates because they are capable of high selectivity.

Mechanical flotation cells can be broken down into two broad categories based on how air is introduced to the cell. In a self aspirated flotation cell air is introduced to the slurry, the vacuum created by the rotorusing . In a forced air flotation cell air is generated external to the cell by a low pressure blower,, and pumped down the

This class of flotation devices is sometimes referred to as "two-stage flotation cells." Eriez developed and patented its two-stage device, called the StackCell in 2008. Today, the company has more than 30 fullscale installations in coal flotation. A cut-away of the Stack- Cell is shown as Figure 2. The design features a tank within a tank.

1. Introduction. With the continuously high demand for energy and metals around the world, high-grade ore deposits are sharply depleted (Peng and Bhambhani, 2021).This forces the industry to transition into the processing of complex and lower grade ores (Mudd, 2010).As ore grades decline, more challenges arise in mineral processing …

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.

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.
