— In a flotation cell, the size of air bubbles decreases with increasing the frother concentration. This is due to a lowering of the interfacial (gas–liquid) tension and the stabilization of the thin liquid film formed between colliding air bubbles, hence preventing their coalescence (Grau and Laskowski, 2008, Khoshdast and Sam, 2011, Khoshdast et …
