    All processes are used in Aluminium metallurgy but the Hoopes process is a metallurgical process, used to obtain the aluminium metal of very high purity. The Bayer process is the principal industrial means of refining bauxite to produce alumina (aluminium oxide). The Hall–Héroult process is the major industrial process for smelting aluminium.  Serpeck's process  is used for the purification of bauxite ore containing silica  as the main impurity
