摘要

Most electrolytic magnesium metal production utilizes a magnesium oxide feed material. This requires hydrochloric acid for feed dissolution, which in turn requires cleaning, drying, compression and combustion of the chlorine gas produced in the electrowinning process. The latter operations constitute a significant part of the capital investment and operating cost of an electrolytic magnesium facility. This work explores the concept of producing hydrogen chloride gas on the anode in molten salt electrowinning of magnesium metal, which in addition to offering capital savings can also lower the cell voltage by one volt (1 V) compared to chlorine gas evolution. The experimental cell used in the testwork is described and results are presented. The decrease in cell voltage was confirmed indirectly.
