    The Cell produces fast mineral flotation rates, especially for very fine mineral particles. It produces high concentrate grades from fast floating liberated particles and is able to do this from a single stage of flotation. The high carrying capacity of the Jameson Cell is particularly beneficial when high yields (mass pulls) are required, such as in recleaning in metals flotation and in the

    Turning to flotation reagents, Frank Cappuccitti, President of Flottec explains that Flottec and Cidra are “working very hard jointly on developing instruments that will measure hydrodynamics in the flotation cell and circuit in a bid for better flotation control. This would be a great step forward in using a combination of reagents and sensors to optimise flotation systems. It brings

    BENEFITS OF HIGH INTENSITY FLOT ATION AT Jameson cell

    The Jameson Cell is a high intensity flotation device, which utilises induced air from atmosphere. It was developed jointly by Mount Isa Mines and Prof. GJ Jameson of the University of Newcastle in the 1980’s. It is proven to generate fine bubbles, in the order of 300 to 500µm, in a high intensity, high shear and compact zone contained in the downcomer. This aerated mixture exits the

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.

    Froth Flotation Circuit Design And Basic Testwork

    The conditioned mineral slurry is then processed in flotation cells, which are essentially agitated tanks into which finely-dispersed air bubbles are introduced. The desired hydrophobic mineral will then attach to the air bubbles and float to the top of the flotation cell, where it will be skimmed off as a mineral-laden froth. The remaining unfloated mineral slurry will be discharged as tailings.
