  • Flotation Machines - Mineral Processing Metallurgy

    Whatever flotation machine design is chosen, it must perform a series of complicated functions. Some of the more obvious are: Good mixing of pulp. To be effective, a flotation machine should maintain all particles uniformly in suspension within the pulp, including those of relatively high density anchor size. Good mixing of pulp is required for maximizing bubble-particle frequency.

    Coal flotation is commonly carried out with a combination of an oily collector (e.g. fuel oil) and a frother (e.g. MIBC). All coal flotation systems require the addition of a frother to generate small bubbles and to create a stable froth (Table 12.2). Typical addition rates for frothers are in the order of 0.05–0.3 kg of reagent per tonne of ...
