From Microbubbles to Nanobubbles: Effect on Flotation

The flotation at 4 bar (mostly by MBs) was faster (0.07 cm s −1) due to the high lifting power of the MBs but left a higher residual total iron content of 1.7 of mg/L. The flotation with isolated NBs (>108 bubbles mL −1) attained 91% iron removal due to "flotation" following NBs entrapment and the decrease of the relative density of the ...

Introduction. Froth stability plays an important role in determining selectivity and recovery in flotation (Farrokhpay, 2011). It should be noted that froth with very high stability is not desirable because in addition to recovering the particles attached to the bubbles, it creates favourable conditions for entrainment (Zheng, Franzidis, and Johnson, 2006).
