Mineral processing | metallurgy | Britannica

Mineral processing, art of treating crude ores and mineral products in order to separate the valuable minerals from the waste rock, or gangue. It is the first process that most ores undergo after mining in order to provide a more concentrated material for the procedures of extractive metallurgy.The primary operations are comminution and concentration, but there are other important operations ...

Processing of primary and secondary raw materials ...

2013-07-08 · In the sequence “agitating - mixing - grinding” the raw material was mechanically treated and a deagglomeration and deaggregation of the starting material was achieved step by step. A comminution of up to a particle size x 50;3 of 100 nm was achieved in an agitator ball mill with a maximum specific energy input of 3.7 kWh/kg.

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 ...
