The high volumetric throughput resulting from the vastly reduced residence time in the cell allows for drastically reduced equipment sizes when compared to conventional flotation cells.
Flotation Cells are provided with openings in the partition plates for by-passing the pulp from cell to coll without the pulp circulating through each hood feed pipe. In normal operation these partition gates are left closed; however, this arrangement is advantageous when large tonnages are fed to the flotation machine.

Jameson Cell has accurate scale-up reliability and is the real-word specification in any and all duties within a flotation circuit: rougher and scavenger duty; cleaner and cleaner scavenger duty. In fact, a single Jameson Cell has successfully replaced a traditional circuit of cells; and unlike other competing cells, it has no moving parts.
In principle, the cell functions as a shallow flotation cell. As the air and pulp are hydrau-lically lifted to the top of the pulp recircula-tion well, the mineral laden air bubble has only to travel a short distance on its own to the froth overflow level. Above are illustrations of three flotation cells. 14.2 m3 (500 cu.ft) cell 2.8 m3 (100 cu ...
Flotation is one of the most important physicochemical processes for mineral separations and other recovery operations. Flotation machines have been developed since the beginning of the 19 century and are still under intensive research and development. The devised cell is a combination of the Canadian Column Flotation Cell and Partridge …
Gas dispersion measurements, such as bubble size, gas hold-up and gas velocity, can be used to characterize the hydrodynamic conditions in the pulp phase of a …

Optimizing Flotation Cells. H ow a flotation cell works . Flotation Cells (Froth Flotation) were developed to separate and recover high value Sulphide ores from low grade ore bodies. The ore is crushed and milled at the concentrator in a process known as comminution, where the mineral is in suspension in slurry.
Concorde Cell™ sets a new benchmark in high intensity pneumatic flotation by recovering unachievable fine and ultra-fine particles.
Imhoflot pneumatic flotation technology has evolved through 25 years of industrial applications. This has led to the development of the patented Imhoflot G-Cell where centrifugal forces are used in the cell to quickly separate the phases after mineral collection and therefore considerably reducing the size of vessels required.
In conventional flotation cells a certain amount of energy is required to meet the basic requirements for flotation (air dispersion, solids suspension and particle-bubble collision). This paper investigates how that energy is dissipated in the flotation cell to determine the most efficient use of the imparted energy.
The Direct Flotation Reactor (DFR) is a flotation cell that works on the principle of preventing the formation of a froth and froth slurry interface. Independent bubbles are removed from the collection zone in a gas …
In its essentials, a flotation cell must provide for two main functions. First, it must supply air adequate in quantity and quality for satisfactory process kinetics.
