The extraction of magnesium from seawater is promising given that approximately 0.13% of seawater is magnesium (Natasha et al., 2017). The major issue is the energy consumption, as over 10 kWh is required for every kg magnesium metal (Liu et al. 2018). Additionally, magnesium extracted from seawater contains many impurities like sodium, …
