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 AlCl 3 ; optionally converting AlCl 3 into Al(OH) 3 ; and heating said AlCl 3 or said Al(OH) 3 under conditions effective for converting AlCl 3 or Al(OH) 3 into Al 2 O 3 and optionally recovering gaseous HCl so-produced. Aluminum ions so purified are thus useful for preparing various types of alumina.
