Question

How is the element Magnesium made or acquired?

Answer 1

Hint : Magnesium is an extremely important mineral. It participates in hundreds of chemical reactions in your body and aids in the maintenance of good health, but many people do not meet the reference daily intake (RDI) of 400 mg (1). However, you can easily meet your daily needs by eating magnesium-rich foods.

Complete Step By Step Answer:
Dolomite ore is thought to be one of the best ores for obtaining magnesium and its various compounds. Dolomite ore ( $CaC{{o}_{3}},MgC{{o}_{3}}$ ) can be thought of as a combination of one layer of $CaC{{o}_{3}}$ calcite and one layer of $MgC{{o}_{3}}$ magnesite.
Dolomite occurs in metamorphic rocks primarily in contact with magnesia or dolomitic limestones, where it can recrystallize to form dolomite marble. Dolomite, on the other hand, differs from limestone in that it can contain up to 45 percent of $MgC{{o}_{3}}$ .
Ores of dolomite $CaMg{{(C{{O}_{3}})}_{2}}$ are another important commercial source. It is worth noting that the presence of magnesium as a carbonate exemplifies a chemical principle. Because most carbonates are insoluble, we can mine metal carbonates.
After mining the ore, the magnesium ion must be reduced to produce the metal. The ores are treated with (massive) amounts of hydrochloric acid to produce $MgC{{l}_{2}}$ . After that, the salt is electrolytically reduced (which process must run up a tremendous power bill). The resulting metal is strong, light, and a valuable commodity.

Note :
Magnesium is primarily obtained through the electrolysis of magnesium chloride, which can be found in virtually unlimited quantities in the oceans. It is derived from salt lake brines in the United States. Magnesium can also be obtained in trace amounts from the magnesium-containing minerals dolomite, magnesite, kieserite, and brucite. Carnallite, cordierite, and diopside are other magnesium-containing minerals. Magnesium is mined in China, North Korea, Russia, Austria, Greece, and the USA.
