While Dow has been pioneering the extraction of magnesium from water, others have been studying how to extract magnesium from rock. TVA scientists are working on the Carolinas' 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...
...Macedonia. "Of the surrounding hills one stood alone, magnificent in sharp austerity of cliff and pyramid: it is called 'the witness of God.' " Author West and her friends arrived at the Sheep's Field by car. "When we got out we were so near the rock that we could see its colour. It was a flat-topped rock . . . rising to something like six feet above the ground, and it was red-brown and gleaming, for it was entirely covered with the blood of the beasts that had been sacrificed on it during the night. . . . The colour...
...Hughe Montgomery Knachtbull-Hugessen, British Ambassador, who was shot up when a Japanese plane strafed his car near Shanghai (TIME, Sept. 6, 1937), reported that three men operating a large slingshot barely missed him with a fist-size rock...
Today copper is 12? a lb., not 16?. Yet the Morenci ores, though low-grade, will still yield a profit. When production starts, nine 125-ton electric locomotives will haul 75,000 tons of rock from the pit each day, dump 50,000 tons of waste into the canyons, spill the rest into ore bins. Each ton of ore will yield 21 lb. of copper-a daily smelter production of around 260 tons...
...young men continued their study of the rocks. When they rounded the next bend, they again say the maidens, and each was looking under a ledge. When the maidens saw the young men, they stopped looking under the ledges. And so the two groups continued to weave in and out among the inlets and coves of the coast of Swampscott. After some time, the Leader, coming upon a very large rock extending far out into the sea, walked to its very edge and shouted: "Siluvian amygdaloidal pyroxenite." There was no answer...
