Froth flotation is a process for separating minerals from gangue by taking advantage of differences in their

hydrophobicity. Hydrophobicity differences between valuable minerals and waste gangue are increased through

the use of surfactants and wetting agents. The selective separation of the minerals makes processing complex that is, mixed) ores economically feasible. The flotation process is used for the separation of a large range of

sulfides, carbonates and oxides prior to further refinement. Phosphates and coal are also upgraded (purified)

by flotation technology.

Operation Principle:

Froth flotation commences by comminution (that is, crushing and grinding), which is used to increase the surface area of the ore for subsequent processing and break the rocks into the desired mineral and gangue in a process known as liberation, which then has to be separated from the desired mineral. The ore is ground into a fine powder and mixed with water to form a slurry. The desired mineral is rendered hydrophobic by the addition of a surfactant or collector chemical. The particular chemical depends on which mineral is being refined. As an example, SEX is added as a collector in the selective flotation of galena and sphalerite, after the addition of other flotation reagents. This slurry (more properly called the pulp) of hydrophobic particles and hydrophilic particles is then introduced to a water bath which is aerated, creating bubbles. The hydrophobic particles attach to the air bubbles, which rise to the surface, forming a froth. The froth is removed and the concentrate (con) is further refined.

Flotation can be performed in rectangular or cylindrical mechanically agitated cells or tanks, flotation columns.

Mechanical cells use a large mixer and diffuser mechanism at the bottom of the mixing tank to introduce air and provide mixing action. Flotation columns use air spargers to introduce air at the bottom of a tall column while introducing slurry above. The countercurrent motion of the slurry flowing down and the air flowing up provides mixing action. Mechanical cells generally have a higher throughput rate, but produce material that is of lower quality, while flotation columns generally have a low throughput rate but produce higher quality material.

Specification:

Flotation is widely used in rock mineral separation especially for the rock gold, copper, zinc, lead, Pyrite etc.
