    LIMONITE : Limonite, a compound of iron, oxygen and hydrogen, is a yellowish brown to dark brown or black mineral. Impure limonite occurs in many counties in the state, often appearing as a ru st-like material staining sand and binding it together. A deposit of fairly high grade limonite is known to exist near Chiefland in Levy County.

  • Limonite: an iron oxide used as pigment and iron ore

    Limonite deposits are usually too small and too impure for use in modern metallurgy. Names such as "brown iron," "brown hematite," "bog iron," and "brown ocher" have been used by miners to relate limonite with its potential uses. Their use has declined significantly, and the name "limonite" is now used for these various materials.
