• Dawsonite - Wikipedia

    en.wikipedia.org/wiki/Dawsonite Dawsonite is a mineral composed of sodium aluminium carbonate hydroxide, chemical formula NaAlCO 3 (OH) 2.It crystallizes in the orthorhombic crystal system.It is not mined for ore. It was discovered in 1874 during the construction of the Redpath Museum in a feldspathic dike on the campus of McGill University on the Island of Montreal, Canada. It is named after geologist Sir John William ...

    www.britannica.com/science/dawsonite Dawsonite, a carbonate mineral, NaAlCO3 (OH)2, that is probably formed by the decomposition of aluminous silicates. Of low-temperature, hydrothermal origin, it occurs in Montreal, where it was first discovered; near Monte Amiata, Tuscany, Italy; and in Algiers. In the oil shale near Green River,

    pubs.acs.org/doi/10.1021/acsearthspacechem.8b00121 Dawsonite is a hydrated sodium aluminum carbonate with a chemical formula of NaAl(CO 3)(OH) 2.Although dawsonite is composed only of five elements that occur abundantly in the Earth’s crust, natural occurrences of dawsonite are rare, indicating unique formation conditions.

    agupubs.onlinelibrary.wiley.com/doi/full/10.1029/2011GL046845 [1] Computer simulations predict dawsonite, NaAlCO 3 (OH) 2, will provide long‐term mineral sequestration of anthropogenic CO 2 whereas dawsonite rarely occurs in nature or in laboratory experiments that emulate a carbon repository. Resolving this discrepancy is important to determining the significance of dawsonite mineralization to the long‐term security of geologic carbon sequestration.

Higher aqueous aluminum concentrations in the experiment suggest that dawsonite or diaspore is less stable than predicted. Simulations employing an alternate database, thermo.dat, correctly predict dawsonite and dawsonite‐

Most of the extract­ able alumina originates from decomposed dawsonite. With an average dawsonite content of 10 to 12 pct, the extractable alumina content is only about 4 to 5 pct.
