It may not be the heydays of the old Tri-state district, when King Jack ruled over Joplin, but zinc is still produced in Missouri.  Today, zinc is produced as a byproduct of lead mining in the Viburnum Trend, which produces enough to keep Missouri the number two zinc producer in the nation. Zinc is an important industrial metal due to its resistance to corrosion, it is used in galvanizing or Parkerizing steel against rust and corrosion; in alloys, to create brass, nickel-silver and soldering compounds, in paints as a white pigment, and skin medicine as an active ingredient.  For more information about zinc, contact the Geologic Resources Section at 573-368-2143 or email.
