...already alarmingly dependent on imports for many of its most critical industrial raw materials. In all, 98% of America's manganese, 97% of its cobalt, 93% of its aluminum and 91% of its chromium come from foreign ores. More than 50% of its tin, nickel, zinc and tungsten ores are also imported. The supply of several of these materials is susceptible to interruption because they come from either the Soviet Union or from unstable southern African nations that suffer serious internal troubles. The most important minerals include...
...Chromium. The major deposits of this material, used in stainless steel, ball bearings and surgical equipment, are in South Africa, Zimbabwe Rhodesia and the Soviet Union. Says Allen G. Gray, technical director of the American Society of Metals: "A cutoff of our chromium supply could be even more serious than a cutoff of our oil supply. We do have some oil, but we have almost no chromium...
Though no modern industrial nation can be a totally self-sufficient island, the U.S. has little choice except to build safe stockpiles of those essential materials, such as chromium and manganese, that are found in quantity in only a few countries. The mineral-rich American West, Alaska and the oceans bordering the U.S. contain vast unmined natural resources that hold the longer-term promise of more domestic sufficiency and security. These minerals often remain in the ground or under water because of ecological concerns or the higher profits that firms can earn abroad. Steep mining taxes in Minnesota, Montana...
...financially dependent on Pretoria, which will also advise on BophuthaTswana's diplomatic and defense affairs. Nonetheless, the new homeland has a considerable economic potential: at present it accounts for two-thirds of the total platinum production in the Western world. It is also rich in asbestos, granite, vanadium, chromium and manganese. By 1979 the homeland should be receiving direct mining revenues of about $30 million a year. But only 10% of BophuthaTswana's total land area is arable, and much of that is covered with scrub brush...
...Pain. Developed by Dr. Theodore Waugh, 48, an orthopedic surgeon at the University of California at Irvine (U.C.I.), the new joint is a two-piece arrangement that weighs only five ounces. One part of Waugh's "U.C.I, ankle" is an inverted T made of a chromium and cobalt alloy with a concave tip. The other part is an alloy half dome...
