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.
