    Calcination of dolomite involves heating the raw material at sufficient temperature in order to release the carbon dioxide from its carbonate minerals. This process is commonly conducted in a rotary kiln. There have been a number of calcination studies in a laboratory scale, but the study of dolomite calcination in a larger scale is very scarce.

  • CHAPTER 2 MINERAL INDUSTRY EMISSIONS

    There are two broad pathways for release of CO2 from carbonates: calcination and the acid-induced release of CO2. The primary process resulting in the release of CO2 is the calcination of carbonate compounds, during which, through heating, a metallic oxide is formed. A typical calcination reaction, here shown for the mineral
