...world's supply of radium. (The uranium in the waste tailings from the mines was thrown away.) When richer radium-bearing ores were found in the Belgian Congo, the mines closed. Later, the area became a major producer of vanadium, also from carnotite, a metal used to harden steel. But not until World War II did its biggest boom develop. Tailings from radium and vanadium plants provided uranium for the first atom bombs...
...that sometimes galls Rocky is in the discipline of training for each fight. It means not seeing his young wife for six to eight weeks of rigidly controlled rest and exercise. "You gotta take orders, you know," Rocky says. "You gotta harden up your body so you can take a punch better. That discourages the other guy."

First a fort, then a town, by 1896 it was a contented city of 285,000 which brewed a little beer, made a few families wealthy through lumbering and mining, turned out carriages and stoves and let its arteries harden in dignity.

...problem is too big for a quick & easy solution. The U.S. consumes more than 50% of the world's strategic raw materials. But the U.S. is also the world's biggest producer of raw materials. As much as 70% of the world supply of molybdenum (used to harden steel for cutting tools) has come from a single mine at Climax, Colo.; the U.S. produces 90% of the world's high-grade sulphur, is the largest producer of copper, exports more cotton than any other country. But in other materials, notably metals like tungsten and cobalt...
