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").

An Overview of Basic Gold Separation Methods - RareGoldNuggets

The flotation method involves mixing your crushed ore with water and then you add frothing agents in a single floatation machine. You then use a tube to release air into the floatation machine. This creates air bubbles to the bottom of the machine and this helps attach hydrophilic materials such as gold to the bubbles and thus float on the water.
