Dow's process of extraction of Mg involves extraction of Mg from sea water. Sea water is concentrated in sun light and is then treated with skaked lime. Magnesium hydroxide is heated in a stream of HCI to give MhCi which is electrolysed to dischate Mg . the mixture is in the ratio 35% MgCI_(2) +50% NaCI + 15% CaCI_(2). NaCI_(2) and CaCI_(2) are added to lower the fusion temperature and to increase the conductance.
