METHODS FOR PURIFYING ALUMINIUM IONS

---

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.
