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.~
