Magnesium Processing
Magnesium is a metal that is found in abundance throughout Earth’s crust. It is plentiful in major mineral deposits, such as ores of dolomite, carnallite and magnesite. However, it is difficult to process and work with due to its high melting point and reactivity. While magnesium is the 8th most abundant element in the universe, it has to be extracted, purified and processed into a useful form before it can be used.
The common method to isolate and refine magnesium is through the Pidgeon Process. This process utilizes carbon reduction of magnesite ore, which is heated to high temperatures in the presence of iron, in order to form magnesium. The iron absorbs all of the oxygen, leaving pure magnesium behind, which is then extracted.
Once purified, magnesium is either produced in its pure form or it is formed into alloys with other metals. Pure magnesium is malleable and ductile and is used for casting and in the creation of structural components. Compounds of magnesium are usually produced in powder form, which is then used in a variety of applications, including antacids, catalysts, fertilizers, flammable accelerants, optical components and many more.
The production of magnesium alloys involves combining it with other metals in order to make metals with better properties. Magnesium can be combined with aluminium and zinc to create an alloy that is used in the manufacture of automotive components, aircraft parts and recreation items. It was widely used in automobile manufacturing during the early 20th century. Magnesium is also combined with manganese and nickel to create an alloy that is widely used in the aircraft industry, as it has high strength and energy-absorption capabilities.
Magnesium alloys have also been used in many medical and cosmetic applications. The alloys are malleable and formable and can be easily included in implants, casts and prosthetics. Magnesium has also been included in toothpastes and cosmetics, as it can help reduce inflammation and redness in the skin.
In addition to its industrial and medical uses, magnesium also plays a role in fire protection and safety. Magnesium filings are often used in flares and pyrotechnics, and they can also be used to extinguish fires, since magnesium burns at an incredibly hot temperature. This has made it invaluable in aerospace and marine applications, as magnesium has been used to create fire-resistant components for aircraft and ships.
Magnesium is an essential element and is used for a variety of applications around the world. From its use in the creation of alloys to its role in medical and safety applications, magnesium is essential for many industries today. Its extraction and processing, through the use of the Pidgeon Process, has allowed us to use this abundant metal in a variety of industries.
