Electroplating Electroplating is used to coat one metal with another metal by using electrolysis. Electroplating is usually done to improve the appearance of the metal or prevent the corrosion of the metal. Chromium plating is used to prevent iron from rusting. The
Hall–Héroult process - Wikipedia
The Hall–Héroult process is the major industrial process for smelting aluminium. It involves dissolving aluminium oxide (alumina) (obtained most often from bauxite, aluminium''s chief ore, through the Bayer process) in molten cryolite, and electrolysing the molten salt bath, typically in a purpose-built cell. The Hall–Héroult process
steps involved in the extraction of aluminium from its ore
The extraction of aluminium from its ore takes place in two stages, purifiion stage and electrolysis stage. The diagram below shows the set up for the electrolysis stage. i) Name the ore from which aluminium extracted ii) Name one impurity which is removed at the purifiion stage.
