  • METHODS FOR PURIFYING ALUMINIUM IONS
    Publication number: 20170260062
    Abstract: There is provided a process for purifying aluminum ions comprising: reacting an aluminum-containing material with an acid so as to obtain a composition comprising aluminum ions; precipitating said aluminum ions in the form of AlCl3; optionally converting AlCl3 into Al(OH)3; and heating said AlCl3 or said Al(OH)3 under conditions effective for converting AlCl3 or Al(OH)3 into Al2O3 and optionally recovering gaseous HCl so-produced. Aluminum ions so purified are thus useful for preparing various types of alumina.

  • Methods for purifying aluminium ions
    Patent number: 9534274
    Abstract: There are provided processes for purifying aluminum ions. Such processes comprise precipitating the aluminum ions under the form of Al(OH)3 at a first pH range; converting Al(OH)3 into AlCl3 by reacting Al(OH)3 with HCl and precipitating said AlCl3; and heating the AlCl3 under conditions effective for converting AlCl3 into Al2O3 and optionally recovering gaseous HCl so-produced. The processes can also comprise converting alumina into aluminum.
