  • 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

    Mineral concentration is important because metallurgical, chemical, and other industrial processes are based on the treatment of products (concentrates) that are enriched in useful components. For example, the content of lead in ore is usually less than 1.5 percent, whereas smelting requires a metal content of
