Froth Flotation Process Detailed Explanation With

What Is Froth Flotation Process?Method of Froth FloatationBasic Principle of Froth Flotation ProcessMechanism of Froth Flotation ProcessFroth flotation is one of the most popular operational processes for mineral beneficiation. In ore/mineral beneficiation, froth flotation is a method by which commercially important minerals are separated from impurities and other minerals by collecting them on the surface of a froth layer. Flotation is the process of separation of beneficial minerals from a mixture by creating froth on which minerals separate out. ThiSee more on byjus.com

OverviewPrinciple of operationHistoryIndustriesScience of flotationFlotation equipmentMechanics of flotationChemicals of flotation

Before froth flotation can work, the ore to be treated is reduced to fine particles by comminutionso that the various minerals exist as physically separate grains. This process is known as liberation. The particle sizes are typically less than 0.1 mm (100 µm), but sometimes sizes smaller than 710 µm are required. There is a tendency for the liberation size of the minerals to decrease over time as the ore bodies with coarse mineral grains that can be separated at larger sizes are depleted and replaced by ore bodies th
