In many cases, carbon cannot be used to reduce the metal oxide to the metal as the metal reacts with carbon to form the carbide instead. It is possible to avoid this problem by first converting the ore to the chloride, and then reducing the chloride with a more reactive metal such as magnesium or sodium. This is the method used to extract titanium.
11-04-2020· 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.

27-04-2021· This article describes three magnesium extraction methods: the Horizontal Pidgeon Process, the Vertical Pidgeon Process, and aluminothermic reduction.
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."

16-09-2013· Magnesium Extraction By Thermal Reduction Methods. The only ores used in the production of magnesium with thermal reduction technology are dolomite and magnesite. These ores are extracted through customary mining methods, mainly through open mining.The ore extracted from the mine undergoes calcination at temperatures of 700–1,000°C.
01-12-2014· For high magnesium and calcium containing bitterns or brines solvent extraction or ion exchange can be used. After selective stripping/elution lithium can be precipitated out. A combined process consisting of solar evaporation and ion exchange for the extraction of lithium was proposed by Steinberg and Dang, 1975, Steinberg and Dang, 1976 .
Electrolysis Extraction: Used to extract metals above carbon in the reactivity series. Reactive metals are hard to reduce so need a powerful method of extraction, which is electrolysis. Extracted by electrolysis of the molten chloride or molten oxide.
Extraction and Uses of Metals. Metals are extracted from their ores using a method dependent on the position of the metal in the reactivity series. More reactive metals are extracted using electrolysis while less reactive metals can be heated with carbon. Other elements can be mixed with metals to produce alloys with different properties.
