USGS Minerals Information: Magnesium

Magnesium oxide and other compounds also are used in agricultural, chemical, and construction industries. Magnesium metal''s principal use is as an alloying addition to aluminum; these aluminum-magnesium alloys are used mainly for beverage cans. Magnesium alloys also are used as structural components of automobiles and machinery.

Zinc - Wikipedia

2019-4-17 · Zinc is a chemical element with syol Zn and atomic nuer 30. Zinc is a slightly brittle metal at room temperature and has a blue-silvery appearance when oxidation is removed. It is the first element in group 12 of the periodic table. In some respects zinc is chemically similar to magnesium: both elements exhibit only one normal oxidation

What Are the Functions of Calcium in the Body? - …

2  · Calcium is tightly linked to many of the roles that vitamin D plays in the body. In bone health (and other physiologic systems), calcium is a key player. Calcium is a mineral that must be constantly eaten to build bone and maintain the blood level of calcium. When people hear about calcium, they think “bone.”
