minerals, but when the concentration of valuable minerals or metals is too low to justify mining, it is considered a waste or gangue material. Within an ore body, valuable minerals are surrounded by gangue and it is the primary function of mineral processing, to liberate and concentrate those valuable minerals. 1.2 Run-Of-Mine Material and Minerals
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 ...
The application of thickener in the mining industry. 1. Dewatering operation of concentrates of red ore minerals such as hematite.
