    OverviewGallerySee alsoBibliographyExternal links

    Smithsonite, also known as turkey fat or zinc spar, is zinc carbonate (ZnCO3), a mineral ore of zinc. Historically, smithsonite was identified with hemimorphite before it was realized that they were two different minerals. The two minerals are very similar in appearance and the term calamine has been used for both, leading to some confusion. The distinct mineral smithsonite was named in 1832 by François Sulpice Beudant in honor of English chemist and mineralogist James Smithson(c.1765–1829), whose bequest est

  • Wisconsin Geological Natural History Survey » Smithsonite

    At one time smithsonite was a major zinc ore mineral in the state. Eventually mining worked through these surficial deposits and zinc production shifted to the mostly unaltered sphalerite found at depth. Smithsonite, however, was encountered in blankets and veins reaching well below the present groundwater table (Heyl et al., 1959).
