Mineral CO2 sequestration by carbonation of industrial residues

The present report deals with the applicability of potential products from mineral sequestration of carbondioxide.

Depending on the route of sequestration chosen, different reaction products will be formed. Direct sequestration will result in a carbonate, olivine, silica mixture, which is practically inseparable and will have little application possibilities. In a two step sequestration, strong acid magnesia extraction followed by magnesium hydroxide recovery and subsequent carbon dioxide sequestration, reaction products can easily be separated in different stages and washed.
