The Concorde Cell is a high-intensity pneumatic flotation cell dedicated to fines and ultrafines. Its development by Professor Graeme Jameson and later on by was driven by two considerations: a reduction in bubble size and an increase in the shear rate and energy dissipation rate increases the particle–bubble collision and attachment …

Battersby et al. used pneumatic Imhoflot G-Cell flotation cells in which pico bubbles are used to obtain fine nickel and zinc. It is stated that when compared to classic flotation cells, an increase at the rate of 20% in zinc obtaining efficiency and a boost at the rate of 30% nickel obtaining efficiency are achieved.

In the Jameson cell slurry and air are introduced at the top which proceeds downward in the downcomer and forms a liquid jet. Consequently, air is entrained into the plunging jet because of the vacuum effect and generates a large number of tiny bubbles as a result of high shear rate [55].In the downcomer region, the collection of particles on …

Bubble sizes that are discussed in the flotation area of current literature are usually in four size groups. The typical bubble size in conventional flotation machines is found to be in the range close to 1 mm, such as the data reported by several researchers which were 600–2500 μm (Rodrigues et al., 2007), 800–1600 μm (Shao, 2004), and …

Flotation machines constitute the basic equipment for useful minerals recovery from non-ferrous ores and other raw materials by flotation. They can operate also as individual flotation cells. Flotation Cells (Froth Flotation) were developed to separate and recover high-value Sulphide ores from low-grade ore bodies. The Flotation Cell is aerated to …

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 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).
