566 MINERALS YEARBOOK, 1978-79 TECHNOLOGY Two series of papers were published in 1978-79 reviewing magnesium metal market conditions and current aspects of magnesium metal techno1ogy.2~ An additional group of papers described the use of magnesium in stee1-making.~ The principles of a solar ponding system for the production of magnesium chloride suitable for electrolytic production of magnesium metal was described.~ A method was described that supplied pure anhydrous magnesium chloride from a concentrated brine solution. The solution was mixed with ethylene glycol and dehydrated in a distillation tower to anhydrous magnesium chloride in glycol. The magnesium chloride was precipitated from the glycol under conditions that precipitated only magnesium chloride from solution. All reagents used in the process were recycled with minimal 1oss.~ A series of supercorroding magnesium alloys that react spontaneously and vigorously in seawater were developed for use as timed releases for ocean engineering applications.~ 1Physical scientist, Section of Nonferrous Metals. 2lnternational Magnesium Association.
