Magnesium is an alkaline earth metal that is never found in nature on its own. Instead, the element is found in seawater, carbon ores, dolomite, carnalite, and other minerals. Thus, the production of the metal in order to create the cutting edge magnesium sheet products begins as soon as the minerals and seawater is harvested. The following are ways that the elemental magnesium is extracted
