Magnesium production

Russian Process Technology. Magnesium production ia the former Soviet Union is apparently done via molten chloride electrolysis (29,30). The basic process uses camaOite [1318-27-0], MgCl2 KCl 6H20, either from natural deposits or as a by-product of processiag natural salt deposits, as its...

Magnesium. This molten salt electrolysis process is the current principal method of magnesium production. The graphite anodes can be either round or rectangular in nature (see Magnesiumand magnesium alloys). 

Research and development efforts have been directed toward improved ceU designs, theoretical electrochemical studies of magnesium ceUs, and improved cathode conditions. A stacked-type bipolar electrode ceU has been operated on a lab scale (112). Electrochemical studies of the mechanism of magnesium ion reduction have determined that it is a two-electron reversible process that is mass-transfer controUed (113). A review of magnesium production is found ia Reference 114. 

Plugging solution for low temperature wells—contains plugging cement, water and molten chloride melt obtained as waste from titanium-magnesium production as complex chloride additive. Patent RU 1091616-C, 1995. 

Thermal magnesium, i.e., magnesium produced by the Pidgeon process earlier and by the magnefherm process at present, constitutes only 30% of the total magnesium production. The rest is produced electrolytically in which the leading examples are (i) the Dow electrolytic reduction process, and (ii) Norsk hydro process. 

I. G. Farben had been almost exclusively responsible for America s frightening shortages of vital Army supplies after our country went to war with Japan. By the time of Pearl Harbor, for example, Farben had succeeded in gathering, through its United States connections, 80 per cent of all magnesium production in the Western Hemisphere. 

Add 10 mL of distilled water to the dry magnesium product in the beaker and stir. Check the mixture with a conductivity checker, and record your results. 

Analyzing Data Use the masses in the table to calculate the mass of the magnesium ribbon and the mass of the magnesium product. Record these masses in the table. 

Two principal methods of producing magnesium metal [264] are being used metallothermic reaction and electrolysis of molten salts. Two-thirds of the magnesium production is obtained by the electrolytic process. On the market there are few producers of magnesium. Therefore, process research and development work have been conducted by these producers, and the results have often been kept secret. Hence, there are few publications in this field, except for patents. 

The Ishizuka Research Institute in Japan [298] has, beginning in 1983, developed a method using a bipolar cell for industrial magnesium production as shown in Figure 28. The bipolar electrodes are made of graphite (anode) with steel plates...
