methods of concentration in mineral processing
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),
