...Yankee savvy at the National University of Mexico, where he supplemented his studies by reading all the U.S. engineering trade magazines he could find. To get some on-the-job training, he took a laborer's job at night at a caustic-soda plant being constructed by Chemico of New York. There, by his own recollection, he picked the brains of every American technician he could find. It was, he says, a "live opportunity...
...comes from Africa, which has abundant supplies. Cyanamid's process, developed by its Chemical Construction Corp. subsidiary, will enable the U.S. to utilize its own low-grade ores more cheaply, and produce pure cobalt from them at a much faster rate. For example, Howe Sound Co., for which "Chemico" is building a new $2,500,000 Utah plant to utilize the process, will be able to turn out 4,000,000 Ibs. a year of pure cobalt, or about 50% of U.S. consumption...
...Chemico's Kansas-born chief engineer, Edward S. Roberts, 48, has been working on the process for 18 years; the company spent some $3,000,000 on research perfecting it. It starts by immersing ground crude ore in chemicals and water to float out some foreign matter. The Chemico method, using ammonia or acid, dissolves this concentrate in an "autoclave," similar to a huge pressure cooker. The resulting ore-bearing liquid is piped through a filter into another pressure vessel, where terrific heat and force precipitate the pure metal as a fine powder...
...only does Chemico's process promise to boost the output of cobalt, but Engineer Roberts says it works equally well with other low-grade ores such as nickel, copper and manganese (but not as yet with iron ores). Moreover, by reducing the amount formerly lost in slag, he says it can increase the pure metal recovered from scrap as much as 15% for copper, 70% for zinc. He predicted it could eventually cut the production costs of cobalt up to 80%, copper and nickel as much...
What is Mind? "There remains however among the happenings met with in such a compound organism as ourselves," says Sherrington, "... a certain residue seemingly not thus resoluble" into chemico-physical energy-systems. This nonmaterial residue is the mind. Sherrington's half-century of studying the human brain has proved that mental behavior is not entirely reflex and thus rooted ultimately in matter (as Pavlov's Soviet disciples believe...
