Selective Flotation Mineral Processing & Metallurgy

Who would think that Selective Flotation of copper, gold, zinc or any metal would required that one must be able to feel pain and recognized and/or admit when it hurts. Flotation mass-pull is a process that is often misunderstood; a learner’s mistake made by non-operating types. You do not need to pump anything in the lab. In selective flotation

Froth flotation Wikipedia

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 crushing and grinding (a process known as comminution) so 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 7–10 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 a
