After the war, cheap magnesium will compete in many markets which were closed to the more expensive metal of 1939. For example...
...small quantities the pure metal was used for photographers' flashlights, for fireworks, for star shells, as a scavenger to remove oxygen from other metals while molten, in organic synthesis. In compounds it was used medicinally for milk of magnesia and Epsom salts. But today the fact that magnesium is only two-thirds as heavy as aluminum and less than one-fourth as heavy as steel has brought it into great demand. And from almost everything except green leaves chemists are now extracting the pure metal-some 24,000 tons this year in the U.S., twice last year...
...imagination : it began mining sea water for magnesium at a great $15,000,000 plant at Freeport, Tex., which by year's end will be sucking in 12,000,000 gallons a day (enough water for a city of 120,000) and turning out 50 tons of metal-a rate of some 18,000 tons a year. This is 50% more than Dow's Michigan wells are producing, yet it would take 316 years at this rate to extract the magnesium from a single cubic mile of sea water...
...Many fabricators would prefer a lightweight metal, if it is as cheap as magnesium promises to be, to any plastic...
...abundant magnesium silicate called olivine, of which 27% is recoverable magnesium (in contrast to sea water's .1%). When this ore is mixed with hydrochloric acid, magnesium chloride is formed which can be treated by electrolysis just like that from water. Because olivine is so rich in metal and TVA power sells cheaply, experiments have been launched at Georgia Tech in the hope of making this a major U.S. source of cheap magnesium...
