Abstract: A heat treatment process of serpentine as raw material for mineral carbonation is provided to efficiently remove -OH groups existing in untreated serpentine and improve crystalline property of the treated serpentine by heat-treating milled serpentine powder at a desired temperature for a constant time period. The heat treatment process comprises the steps of: milling serpentine ore as raw material of mineral carbonation into powder with particle size less than 125 micrometers; heating the powder at above 700deg.C for more than 10 minutes under oxygen or atmosphere; and cooling the powder to ambient temperature. Time for heat treatment of serpentine is more than 10 minutes at a constant heat treatment temperature excluding temperature raising process. The serpentine ore typically includes metal elements such as silicon, magnesium, iron, calcium, aluminum, etc.
