...further leverage on Wilson, Kaunda decided to withhold all hardcurrency payments to Rhodesia, due as its share of the jointly owned and operated railway that is Zambia's lifeline for copper exports and coal and consumer-goods imports. By jeopardizing his own economy, Kaunda hopes to put Wilson over a barrel and force him into more decisive action. To calm Kaunda down, last week Wilson sent Judith Hart, the Minister of State for Commonwealth Relations, to Lusaka. When she arrived, only two minor protocol officers were waiting to meet her, and toward week...
Since late last year, the silver-short U.S. has been forced to mint silverless "sandwich" quarters and dimes containing a central layer of copper between two thin slices of copper-nickel alloy. Now another Government agency has suggested a more direct solution: find more silver. To aid prospectors, U.S. Geological Survey scientists have designed and successfully tested a "silver snooper," a device capable of locating silver deposits buried as deep as three feet below the ground. By shooting a stream of neutrons into the earth, the snooper turns the silver temporarily radioactive, causing it literally to signal its presence...
There was much background to the SEC move. Last year the commission lodged charges against 13 officers, directors and key employees of Texas Gulf Sulphur Co. for taking profitable advantage of advance word about the discovery of a huge Ontario ore field of copper, lead, zinc and silver. Among those charged was Thomas S. Lament, now 67, a retired vice chairman of Morgan Guaranty Trust Co. and a director of Texas Gulf Sulphur...
...method of casting is to pour the metal into ingot molds to harden, strip away the mold, reheat the ingot and roll it into semifinished shapes. Continuous casting eliminates these cumbersome steps. A ladle atop a tower pours white-hot steel into a 2-to-4-ft-deep oscillatfhg copper-lined mold. As the mold bottom is withdrawn, an unbroken billet of barely crusted steel creeps down through cooling water sprays and over rollers to burners, which slice it, still red-hot, into handy lengths. The technique has cut production costs by more than $10 a ton for companies such...
Psychological Effect. Though the effect of such orders will be largely psychological, they might work well. Seldom have traders been so drawn by profit dreams rather than performance reality. Most notable example this month is Calumet & Hecla Inc., a 95-year-old Michigan copper company listed on the New York Stock Exchange. With investors excited by the possibilities of war in Viet Nam and shortages of war-essential copper at home, Calumet & Hecla two weeks ago touched off a run by announcing a 35 million-ton copper ore find in upper Michigan. Remembering quick profits generated by Texas Gulf Sulphur...
