  • Mineral processing - Wikipedia

    Mineral processing can involve four general types of unit operation: comminution – particle size reduction; sizing – separation of particle sizes by screening or classification; concentration by taking advantage of physical and surface chemical properties; and dewatering – solid/liquid separation. In all of these processes, the most important considerations are the economics of the ...

  • Coal - Wikipedia

    Coal is a combustible black or brownish-black sedimentary rock, formed as rock strata called coal seams.Coal is mostly carbon with variable amounts of other elements; chiefly hydrogen, sulfur, oxygen, and nitrogen. Coal is formed when dead plant matter decays into peat and is converted into coal by the heat and pressure of deep burial over millions of years.

    In mineral processing, this is usually water, and wet classification is generally applied to mineral particles that are considered too fine to be sorted efficiently by screening. Since the velocity of particles in a fluid medium is dependent not only on the size but also on the specific gravity and shape of the particles, the principles of classification are important in mineral separations ...
