temperature for calcination of dolomite

  • Performance of Dolomite Calcination in a Bench

    Compared to laboratory scale, the conversion of dolomite calcination at bench scale is obtained at higher temperature. For example, using inert gas, dolomite calcination conversion is at 900 and by using CO2 containing atmosphere, the conversion is 80-90% at 900 C, while the calcination conversion at bench scale at 900 C is 72 %.

  • Calcination

    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 decomposition. A calciner is a steel cylinder that rotates inside a heated furnace and performs indirect high-temperature processing (550–1150 C, or 1000–2100 F) within a controlled atmosphere.
