use of electrolysis in the extraction of metals

Electrolysis

Electrometallurgy is the process of reduction of metals from metallic compounds to obtain the pure form of metal using electrolysis. Aluminium, lithium, sodium, potassium, magnesium, calcium, and in some cases copper, are produced in this way.; Production of chlorine and sodium hydroxide; Production of sodium chlorate and potassium chlorate; Production of perfluorinated organic compounds such
