WebThe extraction of aluminum is a two-step process. First, alumina is extracted from bauxite ore in the Bayer process. Then, pure aluminum metal is extracted from alumina in the Hall–Héroult process. This is an electrolytic process. WebVideo Transcript. Why must the positive electrodes often be replaced in the Hall–Héroult process used in the extraction of aluminum? Aluminum is a very reactive metal. For this reason, aluminum cannot be extracted from its ore by reduction with carbon. A common way to extract less reactive metals is to heat their metal ores with carbon.
