    Cobalt is a critical and strategic metal because of its essential defence related uses and the high degree of U.S. import reliance for its supply. Currently, the United States does not produce any cobalt from domestic mines. Most of the U.S. supply of cobalt is imported from the African nations of Zambia and Zaire CO-4 Recent trends make it desirable to reduce this country8217s dependence on foreign sources of critical metals by developing technically and economically feasible processes for treating domestic cobalt ores.

    Figures 2 and 3 show the effect of oxygen overpressure on the rates of cobalt and iron extractions at 95 C and 10 pct solids. A 100-psi oxygen overpressure produced the best combination of high cobalt extraction rates and minimal iron extraction. Maximum cobalt extraction was achieved in approximately 2 h however, iron extraction continued to decrease slightly at leaching times up to 5 h. As a consequence, subsequent test work was conducted using a 5-h retention time.
