  • 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 density magnetic 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
