Magnesium carbonate (MgCO3) is found in a mixture of natural minerals. It can also be produced in several ways, including pumping carbon dioxide through magnesium oxide or magnesium hydroxide. It is used in pharmaceuticals such as magnesium citrate and as a desiccant to keep hydroscopic products from caking (table salt) and to strengthen rubber and produce dyes, inks, and cosmetics.
