  • the present invention provides a process for carbon dioxide sequestration.
  • Background of the invention The rising carbon dioxide concentration in the atmosphere due to the increased use of energy derived from fossil fuels potentially may have a large impact on the global climate. Thus there is an increasing interest in measures to reduce the carbon dioxide concentration emissions to the atmosphere.
  • carbon dioxide may be sequestered by mineral carbonation.
  • stable carbonate minerals and silica are formed by a reaction of carbon dioxide with natural silicate minerals:
