Arab–Israeli peace projects regional problems of acute shortage of clean fresh water in Jordan, and the rapid contraction of the Dead Sea. A new desalination plant to be built near the Jordanian tourist resort of Aqaba would convert salt water from the Red Sea into fresh water for use in southern Israel and southern Jordan; each region would get eight billion to 13 billion gallons a year. This process would produces about as much brine as a waste product; the brine would be piped more than 100 miles to help replenish the Dead Sea, already known for its high salt content. This would
Brine mining magnesium from the bitterns left after salt precipitation. The Dow Chemical Company began producing magnesium on a small scale in 1916, from deep subsurface brine in the Michigan Basin. In 1933, Dow began using an ion exchange process to concentrate the magnesium in its brine. In 1941, prompted by the need for magnesium for aircraft during World War II, Dow started a large plant at Freeport, Texas, to extract magnesium from the sea. A number of other plants to extract magnesium from brine were built in the US, including one near the Freeport plant at Velasco. At the end of
