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).
