Magnesium
Magnesium is a silvery-white, lustrous, alkaline earth metal with the symbol Mg and atomic number 12
The magnesium industry is a fascinating field that has been growing rapidly over the years. *Global Production* of primary magnesium is dominated by China, which uses the Pidgeon process, a method that is both energy and labour-intensive . This process is well-suited for China due to its abundant resources and low labour costs. However, as labour rates and energy costs increase, magnesium production costs are likely to rise, making it more challenging for China to maintain its dominance in the market.
Magnesium Resources are abundant and can be found in various forms, including seawater, brines, and minerals like magnesite and dolomite . The largest magnesium resources are found in China, Russia, and Korea, with China accounting for 21% of the world's total magnesite resources . The country with the second most abundant magnesite resources is Russia, followed by Korea .
Magnesium Production is a complex process that involves several steps, including the extraction of magnesium from raw materials, refining, and casting ³. The two main methods of magnesium production are the Pidgeon process and the electrolytic process . The Pidgeon process involves heating dolomite ore in a kiln to produce a mix of magnesium and calcium oxides, which are then reduced to magnesium using ferro-silicon . The electrolytic process, on the other hand, involves the electrolysis of fused magnesium chloride to produce magnesium .
Applications of Magnesium are diverse and include the production of alloys, which are used in various industries such as aerospace, automotive, and electronics ³. Magnesium alloys are known for their high strength-to-weight ratio, making them an ideal material for applications where weight reduction is critical ³.
Challenges Facing the Magnesium Industry include the high energy costs associated with magnesium production, as well as the environmental concerns related to the Pidgeon process. However, researchers are working to develop new technologies that can reduce the environmental impact of magnesium production and make it more sustainable.
