How is aluminium extracted by electrolysis
WebElectrolysis. Electrolysis is the process of breaking apart an ionic compound using electricity - it’s used to extract metals from their ores. It’s only used for the most reactive metals though, since the less reactive ones can be extracted by reduction with carbon which is much cheaper and uses less energy. Web4. Electrolysis In the electrolysis department, the zinc contained in the solution is deposited onto aluminum cathodes in a process called electrowinning. This happens by passing an electric current through cathodes and anodes. The cathodes are removed from the cells and the zinc sheets are stripped from the cathodes and sent to casting.
