Principles of flotation | Henan Deya Machinery Co., Ltd.

The process of material being recovered by flotation from the pulp comprises three mechanisms: (1) Selective attachment to air bubbles (or "true flotation"). (2) Entrainment in the water which passes through the froth. (3) Physical entrapment between particles in the froth attached to air bubbles (often referred to as "aggregation").
