Aluminium and titanium. Extraction ¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨ Titanium cannot be extracted from its oxides by reduction with carbon, because titanium reacts with the carbon (to form titanium carbide), so is impure and brittle. Titanium extraction needs several stages of processing.
The extraction of aluminium from bauxite basically involves two main steps : 1) Concentration of bauxite by leaching. 2) Electrolytic reduction of purified Al2O3. Leaching of Alumina from bauxite. Leaching of alumina is done by the Bayer's process.
