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? Blurtit

Answer (1 of 2): "Magnesium is extracted from its ores by one of two processes. In the first, the ore is converted to magnesium chloride (MgCl2),which is then electrolyzed. In the second process, the ore is convertedto magnesium oxide (MgO), which is then treated with the alloy ferrosilicon. The ferrosilicon reacts with magnesium oxide to yield pure magnesium metal."
