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

Flotation Process - an overview ScienceDirect Topics

The flotation process depends on several design and operational variables. We consider a superstructure that includes the following three flotation stages: the rougher, which processes the feed; the cleaner, which generates the final concentrate; and the scavenger, which generates the final tailing, as shown in Fig. (1). This is a simple ...

The less dense ore rises in the froth to be collected, while the gangue sinks to be discarded. Flotation separates the metallic minerals from the gangue this way and – in the case of copper/ molybdenum ores – separates molybdenite from copper sulphide. The resulting MoS 2 concentrate contains between 85% and 92% MoS 2. Further treatment by ...

Zinc smelting - Wikipedia

Zinc smelting is the process of converting zinc concentrates (ores that contain zinc) into pure zinc. Zinc smelting has historically been more difficult than the smelting of other metals, e.g. iron, because in contrast, zinc has a low boiling point.At temperatures typically used for smelting metals, zinc is a gas that will escape from a furnace with the flue gas and be lost, unless specific ...

Mineral processing - Wikipedia

Froth flotation is an important concentration process. This process can be used to separate any two different particles and operated by the surface chemistry of the particles. In flotation, bubbles are introduced into a pulp and the bubbles rise through the pulp.
