FLS coarseAIR™ coarse particle flotation can be installed upstream of rougher flotation to process the coarser fraction of material usually processed in traditional flotation. It can also be used for tailings scavenger/retreatment applications, where it processes the final tailings stream from the plant to capture coarse particles that may have been lost by the conventional flotation circuit.
Based on the design of the REFLUX™ Classifier, the coarseAIR™ cell comprises a low-turbulence, high-density fluidised bed, reducing the probability that coarse mineral particles will travel to the tails. Inclined lamella channels effectively separate ore from gangue by leveraging the boycott effect. No internal parts mean simple operation, reduced energy consumption and lower maintenance requirements compared to conventional flotation cells, while modular accessory equipment has been specifically designed to facilitate simpler implementation.
