Production and General information about magnesium

Extraction of magnesium

The largest deposits are located in USA, Norway and China. In pure form this metal is obtained from the following minerals:

  • magnesite;
  • dolomite;
  • keseric;
  • epsomite.

The Latin name of the element given from the name of the ancient city of Magnesia, near which especially many deposits of the mineral magnesite.

General information about magnesium

For the first time magnesium was obtained in the early nineteenth century by French chemists by recovering its molten KCl. In its pure form is a very light metal with t° boiling 1103 °C, its density is about 1.7 g/cm3 at 20 °C, and melting point = equal to 650 °C. its Surface is covered with the oxide film, which is destroyed at 623 °C, after which Mg is burned.
