Over the last 30 years, more than 350 jameson cells have been installed at operations in 30 countries.Having started out primarily for base metals and adopted early by coal operators, the jameson cell has since expanded to the flotation of zinc, nickel, lead, silver and platinum worldwide, and to a number of industrial and environmental applications.

Baikal said flotation cells with the capacity varying from 20-300 m were expected to be used for flotation beneficiation of ores, while hydrometallurgical processing would employ reactors, high-compression thickeners, modular sx units and ew equipment.The latter is expected to reduce the construction period by 20, baikal noted.

Schreiber says that process control in a flotation plant normally can be onerous with controlling slurry level and froth proving inherently difficult in a row of flotation cells.The slurry level in any cell affects the driving head in adjacent cells and this can easily create unstable control conditions.

A flotation plant can be around 90 and often lower, making flotation one of the least efficient processes in the concentration path.Hence, over the last few decades much research and development has gone into the stabilization and optimization of flotation circuits.Flotation is a process with many inputs and complex interactions.The.
