How Is Magnesium Extracted? - Reference.com

 · 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.

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."

Extraction and uses of metals (GCSE) — the science hive

Ores. Unreactive metals, such as silver and gold, can be found in the Earth’s crust in a pure form, uncombined to other elements.However, more reactive metals, such as aluminium and magnesium, will usually be found combined to another element in a compound.An ore is a rock that contains enough of the metal to make it economically worth extracting.

Types of Extraction | S-cool, the revision website

An ore is usually a compound of the metal mixed with impurities. When the metal is dug up, a method must be used to separate the metal from the rest of the ore. This is called extracting the metal. The method of extraction depends on how reactive the metal is. The more reactive the metal, the more difficult it is to extract from its compound.
