  • Mineral resource classification - Wikipedia

    Mineral resource classification is the classification of mineral resources based on an increasing level of geological knowledge and confidence. Mineral deposits can be classified as: Mineral resources that are potentially valuable, and for which reasonable prospects exist for eventual economic extraction.

  • Mineral processing - Wikipedia

    Industrially, the most common dense media is a suspension of fine magnetite and/or ferrosilicon particles. An aqueous solution as a dense medium is used in coal processing in the form of a belknap wash and suspensions in air are used in water-deficient areas, like areas of China, where sand is used to separate coal from the gangue minerals.
