Flotation behaviour in reflux flotation cell – A critical review
Since ultrafine grinding is an energy-intensive process, the second strategy tends to implement a rougher circuit to process coarser particles (>250 μm) followed by regrinding rougher flotation concentrates to save energy costs (Fosu et al., 2015). In either case, flotation circuits are required to process much finer or coarser feeds nowadays.
