Mineral processing - Concentration | Britannica

Mineral processing - Mineral processing - Concentration: Concentration involves the separation of valuable minerals from the other raw materials received from the grinding mill. In large-scale operations this is accomplished by taking advantage of the different properties of the minerals to be separated. These properties can be colour (optical sorting), density (gravity separation), magnetic ...

Choosing The Correct Gravity Separation Machine

The difference between a g ravity concentrator and the other gravity separation devices previously discussed is the ability to increase the forces on the mineral particles that improve the particles’ settling in a water medium. Instead of relying on one G force (the force of gravity), a spinning device, like a centrifuge, can increase the ...
