Sea water contains small quantities of `MgCl_(2) and MgS_(4)` Sea water is treated with slaked limeto precipitate the dissolved salty as `Mg(OH)_(2)` The `Mg(OH)_(2)` is dissolved in a little quantity of HCI and `MgCl_(2)6H_(2)O` is crystallised from solution. The hydrated `MgCl_(2)` is heated in a current of dry HCl gas to get anhydrous `MgCl_(2)` Pused anhydrous `MgCl_(2)` is subjected to electrolysis. Magnesium deposited at cathode.
Which of the following process is used in the extractive metallurgy of magnesium

A

Fused salt electrolysis

B

Self reduction

C

Aqueous solution electrolysis

D

Thermitt reduction

Text Solution

Verified by Experts

The correct Answer is:
A
Fused salt electrolysis is the process can be used for the extraction of more electro positive metals like Mg.
