gravity seperation of iron

Mineral processing - Wikipedia

Gravity separation is one of the oldest technique in mineral processing but has seen a decline in its use since the introduction of methods like flotation, classification, magnetic separation and leaching. Gravity separation dates back to at least 3000 BC when Egyptians used the technique for separation of gold.

Gravity Concentration - an overview | ScienceDirect Topics

Gravity separation, for instance, may be used to reject a major portion of the gangue, as it is a relatively cheap process. It may not, however, have the selectivity to produce the final clean concentrate. Gravity concentrates therefore often need further upgrading by more expensive techniques, such as flotation.

Gravity Separation - an overview | ScienceDirect Topics

In cases in which the processes of sedimentation and gravity separation are insufficient to cause the settlement of suspended solids, certain chemicals (such as alum, starch, iron materials, activated silica, and aluminum salts) are added to cause settlement of the solids. This process is then called coagulation.
