Industrial Electrolytic ProcessesAluminium ExtractionAluminium is obtained by the electrolytic reduction of its molten oxide,alumina (Al2O3). Because alumina has a very high melting point (2045 C),the mineral cryolite (Na3AlF6) is added to lower the melting point in orderthat the electrolysis may be carried out at about 950 C. The electrolyticcell has carbon anodes and a carbon…
