extraction of metals from ores using electrolysis

  • Electrolysis Definition and Uses (explained with diagram)

    Uses of electrolysis 1. Electrolysis is used in the extraction of metals from their ores. For example, when a current is passed through molten sodium chloride, sodium is deposited at the cathode and chlorine gas is evolved at the anode. Aluminium and potassium are also extracted by electrolysis.

  • Principles and Procedures involved in the Extraction of Metals

    Electrolytic Reduction The more electropositive metals such as potassium, sodium, calcium and magnesium are obtained from their ores by electrolysis which is a strong redox process. During electrolysis, the cathode acts as a reducing region by supplying the electrons to the metallic ions in the electrolyte, resulting in the deposition of the free metal.
