Mineral processing - Wikipedia

Gravity separation dates back to at least 3000 BC when Egyptians used the technique for separation of gold. It is necessary to determine the suitability of a gravity concentration process before it is employed for concentration of an ore. The concentration criterion is commonly used for this purpose, designated in the following equation (where ...

Concentration of Ore - DewWool

There are numerous methods and it is based on the properties of the material(ore). Methods of concentration of ore: Hydraulic washing: In this process, the upward running water stream is used for washing the powdered ore.
