Magnesium Overview. Magnesium is the lightest of all the structural metals with a density that is only twothirds that of aluminium and onequarter that of steel. The main advantage of magnesium is its strength to weight ratio, which is considerably higher than that of competing structural metals.
Jul 15, 2016 · Next Generation Sustainable Magnesium Primary Production. July 15, 2016 looking at magnesium as an alternative or part of the lightweight material mix are still using a reference to the China Pidgeon process based on average GHG values up to The IMA study already indies a lower level for modern Chinese Pidgeon plants down to 19,9 CO
Jul 01, 2008 · LCA of magnesium production LCA of magnesium production Cherubini, Francesco Raugei, Marco Ulgiati, Sergio 20080701 00:00:00 Metallic magnesium is mostly used in lightweight alloys, one of the main purposes of which being to decrease fuel consumption in automotive appliions. Several different production processes are currently used worldwide, and the magnesium production
The crude magnesium is produced mainly by Pidgeon Process in China. Although Pidgeon Process has achieved certain technological advance in the past ten years, it is mainly by sacing energy, environment, and cheap labor. In the 21st century, human activities should be energysaving and environment friendly. The equipment used in the Pidgeon process should be improved as early as
The Pidgeon process is one of the methods of magnesium metal production, via a silicothermic reduction. Practical production requires roughly 3540 MWh/ton of metal produced, which is on par with the molten salt electrolytic methods of production, though above the 7 MWh/ton theoretical minimum.
2. Magnesium production using Pidgeon process in China 2.1. Pidgeon process A plant for magnesium production based on the ferrosilicon process was built in Canada in the early 1940s (Mayer, 1944) to produce magnesium at the rate of ∼4500kg per annum (or 10,000lb per year). This process (Pidgeon and Alexander, 1944)—later known as the
Because the Pidgeon process, which is used to produce magnesium in China, requires lower capital costs than the processes used in the west, it has become paramount for prospective producers to

Development of the Chinese Iron and Steel Industry during the last 20 years with special attention on the use of Magnesium for Hot Metal Desulfurization New Process Technique in Magnesium Die Casting with Better EcoBalance Dr
Thermochemical equilibrium calculations indie the possibility of considerable fuel savings and CO 2 emission avoidance in the three steps of the Pidgeon process: (a) calcination of dolomite (b) production of ferrosilicon from quartz sand, coal, and iron oxide (c) silicothermic reduction of calcined dolomite by ferrosilicon to magnesium. All three steps should benefit from appliion of
Automotive Lightweighting and China Growth Driving Demand for Magnesium. Chinese magnesium companies have invested in process optimization to lower costs. Although China is often viewed as one entity when considering magnesium supply, internally the industry is also highly competitive, with recent increases in cokegas availability
Magnesium carbonate is first converted to magnesium chloride. It is then dehydrated and electrolysed to produce magnesium metal. Timminco produces magnesium using a pyroprocessing technique (Pidgeon process). Dolomite (magnesium/calcium carbonate) is crushed, calcined, and reduced by ferrosilicon in a vacuum retort.
