    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

  • Separation and Concentration Mineral Processing

    Gravity. Gravity Separation is used to separate mineral and gangue with a large difference in their Specific Gravities. Chromite, tin, tantalite and various heavy metals are amenable to this principle. Some gold ores contain Free Gold which can be recovered by gravity separation and this is the traditional method used in artisanal gold mining.
