The theory of froth flotation is complex, involving three phases (solids, water, and froth) with many subprocesses and interactions, and is not completely understood. The process of material being recovered by flotation from the pulp comprises three mechanisms: (1) Selective attachment to air bubbles (or “true flotation”).
