  • Cobalt an overview ScienceDirect Topics

    The average daily intake is approximately ~ 11 μg of cobalt per day. Higher levels of cobalt exposure occur for individuals working in metal mining, smelting, and refining, in industries that make or use cutting or grinding tools, or in other industries that produce or use cobalt metal and cobalt compounds.

  • Cobalt Flotation Recovery

    Therefore, further grinding to liberate the siegenite particles is required, but is limited by the lower size limitations of the froth flotation and by grinding energy considerations. During beneficiation, the cobalt is distributed to the various mill product streams as shown in figure 3.
