Magnesium: extraction-Metalpedia

Magnesium: extraction; Brife introduction; Magnesium is found in solution in sea-water (about 1.3 kg m-3 magnesium) and in natural brines. It is also found extensively in the ores magnesite (MgCO3) and dolomite (MgCO3.CaCO3). Both of the two types of resources can be used as raw materials to manufacture magnesium metal.

How Is Magnesium Extracted? Reference

Apr 11, 2020· Magnesium is extracted in one of three ways. The first is the electrolytic process, which uses magnesium chloride produced from magnesite or seawater. The second is the silicothermic process, which mixes calcined dolomite or magnesite with ferrosilicon alloy. The third involves dissolving magnesite in hydrochloric acid to make magnesium chloride.

magnesium processing Techniques & Methods Britannica

Magnesium (Mg) is a silvery white metal that is similar in appearance to aluminum but weighs one-third less. With a density of only 1.738 grams per cubic centimetre, it is the lightest structural metal known. It has a hexagonal close-packed (hcp) crystalline structure, so that, like most metals of this structure, it lacks ductility when worked at lower temperatures.

How Is Magnesium Metal Produced? ThoughtCo

Nov 24, 2019· Extraction from Sea Salt . Magnesium is also extracted from salt brines, which contains about 10 percent magnesium chloride. The magnesium chloride at these sources still contains significant amounts of water and must be dried in order to make the magnesium chloride anhydrous, before it can be electrolyzed to produce metal.
