How is aluminium extracted by electrolysis
WebIn this working table, we describe the extraction of aluminium from its ore by electrolysis. Q1: Aluminium is usually extracted by the electrolysis of aluminium oxide (AlO)23. Before it can be electrolyzed, aluminium oxide must be melted. However, aluminium oxide has a melting point greater than 2,000 " which is very expensive to maintain. What is WebThe biggest use of electrolysis in metal reduction is for aluminum, with global production exceeding 64 million tons per year - all through electrolysis. In the Hall-Heroult process refined aluminum oxide is dissolved in molten cryolite at a temperature of 1,000 degrees C.
