  • Cobalt and Nickel Recovery From Missouri Lead Belt

    In Missouri ores, the cobalt-nickel-bearing minerals are best characterized by a complex interlock­ ing of siegenite with chalcopyrite, sphalerite (ZnS), and dolomite. Earlier efforts to recover siegenite by flotation were conducted by the Bureau on table middlings from the southeast Missouri Old Lead Belt (£).
