Metal Magnesium was found in early eighteenth Century, has been 200 years of history. Because of the Magnesium and Magnesium alloy with excellent mechanical properties and physical and chemical properties, application of Magnesium in the industry more and more, the demand for more and more high. Therefore, although the Magnesium found up to now only 200 years, the industrial production of the time only 120 years, but Magnesium metal smelting technology has been rapid development.
The method of Magnesium smelting basically has two kinds: 1, from the spinel, brine or seawater will contain Magnesium Chloride solution by dehydration or melting of Magnesium Chloride melt, followed by electrolysis, it is called electrolysis; reduction of Magnesium oxide from carbonate ore by calcination resulting in heat two, ferrosilicon, this method known as the thermal reduction method.
Here is an introduction to the electrolytic method.
In 1808, scientists David in mercury cathode electrolysis Magnesium Oxide, it is the first time in human history, making the metal Magnesium. Seventeen thirties, Faraday for the first time by electrolytic Magnesium Chloride obtained the metal magnesium. Prior to the start of the first World War, France, Germany, the UK and Canada have achieved Magnesium industrial production, but production an annual output of about hundreds of tons, mainly used for military.
In the 1880s, it was first established by Germany electrolytic tank on an industrial scale, electrolytic without carnallite Magnesium metal production, then created a electrolytic method magnetherm industrialized era. After the continuous improvement in technology and equipment, the world is the adoption of this electrolytic method.
The principle of electrolysis process is at high temperature electrolysis of molten anhydrous Magnesium Chloride, which is decomposed into metal Magnesium and chlorine. High temperature water influence on the properties of molten salt is fatal, therefore, the high purity anhydrous Magnesium Chloride is the key process in Magnesium electrolysis. Different methods of raw materials and processing of raw materials on the basis of the use of electrolysis process, and can be subdivided into several concrete methods: UFA, Magnesium chloride, carnallite method, AMC method, Nuosikefa.
Electrolytic method because of its advanced production technology, has the advantages of low energy consumption, Magnesium smelting method is a very promising. At present, the developed countries more than 80% metal Magnesium by electrolysis.
