Extraction of Magnesium- - Metalcess
Extraction of Magnesium. The extraction of magnesium mainly falls into two groups, i.e. electro-refining (for magnesite) and thermal reduction process (for dolomite). Brief introduction will be given in the following passage. Thermal reduction process is represented by Pidgeon process, named after its inventor Dr. Lloyd Montgomery Pidgeon.
