Abstract
The specific energy consumption for magnesium metal extraction which had been once around 20-22 kWh per kg, has been brought down to nearly 13-14 kWh per kg, in recent years by employing newer cell designs like modular cell. Yet three appears to be further scope for energy reduction, since the thermodynamic energy requirement is only about 6.5 kWh per kg. In further pursuit of energy economy, the importance of many factors like electrolyte circulation, electrolyte composition, Current density, effective separation of anode and cathode products have been identified. New cell designs like bipolar or multipolar type cells have been experimented which claim to be successful enough by bringing down the energy consumption to the desired level of 10 kWh per kg. of magnesium metal
