| Sumario: | Introduction/purpose: Carbonation of minerals (olivine and wollastonite)
and secondary materials such as slag under high pressure in autoclaves
has high importance due to environmetal problems.
Methods: The most important for this process is to have a good
knowledge of the behavior of carbon dioxide in water solution under high
pressure, the precipitation of silica, dissolution of metals such as nickel
and magnesium as well as subsequent filtration.
Results: The carbonation process of olivine und slag under high pressure
(from 40 to 80 bar) in an autoclave was successfully performed at 175°C,
with and without additivies.
Conclusion: A comparative analysis has confirmed better carbonation of
slag (max. 300 kg/ton) in comparison to that of olivine (max. 70 kg/ton)
under the same conditions. |
