Magnesium is a silver-white, elastic light metal and belongs to the alkaline earth metals. Nowadays, fused-salt electrolysis of magnesite and dolomite is mainly done to win magnesium. It is an important component of plant and animal tissues (bones, teeth, chlorophyll).
Magnesium is especially applied in light metal alloys. It is used in the manufacture of pyrotechnic compositions for decades. However, magnesium is also indispensable as a fertilizer.
