calcination gold sulfide ore

  • Calcination

    The IUPAC defines calcination as "heating to high temperatures in air or oxygen" However, calcination is also used to mean a thermal treatment process in the absence or limited supply of air or oxygen applied to ores and other solid materials to bring about a thermal decompositionA calciner is a steel cylinder that rotates inside a heated furnace and performs indirect high-temperature.
