The process has an economic advantage in China, mainly because of China’s low labor costs. Currently, most magnesium metal is produced by batch-type metallothermic reduction processes such as the Pidgeon process. On the other hand, the electrolysis of MgCl 2 is an essential process for economic titanium production even now [115].

Beneficiation and mineral processing of magnesium minerals

Mar 29, 2016  The key to this process relies on the utilization of slag and aluminium, in addition to ferrosilicon, for the reduction of magnesium oxide at higher temperatures, 1700 to 1750oC. Thus, the vapour pressure of magnesium is much higher, at about 0.85 atm. This process has higher productivity than the Pidgeon process.

In the Pidgeon Process, magnesium is produced from calcined dolomite under vacuum and at high temperatures using silicon as a reducing agent. In the process, the finely crushed dolomite (magnesium/calcium) carbonate is fed to rotary kilns where it is calcined, and where the carbon dioxide is driven off leaving a product of calcined dolomite.
