Eriez Flotation is the world leader in column flotation technology with over 900 installations. Columns are used for floating well-liberated ores. Typically they produce higher grade and have lower power costs than conventional cells.
TankCell flotation units are built to last. For instance, Outotec rotors and stators have proven to be the most wear-resistant available. The wide range of available cell sizes enables a compact, economical, and efficient plant design without risk of short circuiting, even for today’s high-tonnage operations.
Froth flotation is a process for separating minerals from gangue by taking advantage of differences in their hydrophobicity.Hydrophobicity differences between valuable minerals and waste gangue are increased through the use of surfactants and wetting agents.
Beyond this, we can also offload overloaded coal flotation circuits as the RFC is a high capacity machine with a small footprint.” Reference: Cole, M.J., Dickinson, J.E., and Galvin, K.P., Recovery and Cleaning of Fine Hydrophobic Particles using the Reflux TM Flotation Cell, Separation and Purifi ion Technology, 240 116641 10 pages 2020
Dahlke and Gomez 2005 showed that in a flotation machine operating in a typical range of the superficial gas velocity J g, the gas holdup e was directly proportional to J g. For a given cell, J g is simply the gas volumetric flowrate Q g, m 3 /s, divided by the area of cross section of the cell, so holdup is proportional to the gas rate Q g.
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 ...
The result is high circulating loads, slow flotation kinetics, poor fines flotation, and poor grade/recovery performance. High intensity inert grinding is an ideal solution to provide both the liberation and improved surface chemistry to achieve a step change in circuit design and performance.
Eriez equipment is used worldwide to achieve better recovery and a higher grade product, while delivering it at a lower cost per ton. MRF/MSW Eriez sets the bar for metals recovery in materials recycling facilities MRF and municipal solid waste MSW plants.
