Chambermaids at Yale's sister college, Smith, also threatened to strike last week over a story in Tatler, the campus funny magazine, about "Maids We Have Known And Loved"-including "one who was four feet wide ... a high-grade moron," another with "monstrous buck teeth." Smith's maids read, bridled, sent a committee to Warden Laura Woolsey Lord Scales demanding an immediate apology. The faculty suspended the Tatler and its editors wrote the maids a penitent letter. "We hope that [the maids] will accept our apologies and that they will be lenient with a sheer creation, unfortunate...
...above their "out-of-pocket" mine costs, about 15? or 16? (depending on the producer). The U.S. will still release the copper to fabricators at 12?, absorb the difference. Similar offers will doubtless soon be made to other high-cost mines (like Miami Copper's low-grade Castle Dome property in Arizona). But the Government doesn't think that any price in the firmament can pry loose much more than 75,000-100,000 tons of additional U.S. copper...
Heretofore the only commercial source of alumina-the oxide from which the pure metal is produced-has been bauxite, about half of which is now imported from British and Dutch Guiana, since there are only some 13,000,000 tons of known high-grade bauxite deposits in the U.S.-about a three-year supply at the present rate of consumption...
Hixson believes his process will not only free the U.S. from dependence on imported ores but will provide alumina cheaper than present methods of extracting it from high-grade bauxite ores. The process takes advantage of the fact that part of the aluminum silicate of which clay is largely composed is aluminum oxide. Boiling hydrochloric acid, Hixson found, combines with the oxide to form aluminum chloride dissolved in water (though it does not affect the silica). Impurities such as iron chloride (formed at the same time) are then removed with an ether. The remaining aluminum' chloride solution is then...
Hixson thinks his process can produce alumina from rich clays and low-grade bauxite for about $31 per ton. Present cost of alumina made from rich bauxite ores is estimated at between...
