Limonite (ˈlaɪ.mə.naɪt) is a mineral that is commonly found in iron ore deposits. The word is derived from the Greek word "leimōn" which means "meadow" or "marsh." This may explain the double "n" in the word, as it could suggest a connection to the word "wet" or "damp." The "ite" suffix in the word indicates that it is a mineral or rock. Therefore, the spelling of "limonite" conforms to the IPA phonetic transcription and the word's etymology.
Limonite is a noun that refers to a type of iron ore consisting mainly of hydrated iron oxide minerals. It might also include variable amounts of goethite, hematite, and other iron oxides. The term "limonite" is derived from the Greek word "leimṓn," meaning meadow or marsh, due to its often yellow-brown or ochre-like appearance resembling these natural settings.
Limonite commonly occurs as a secondary mineral formed through the weathering of sulfide minerals such as pyrite or marcasite. It is typically found near the surface in areas with high moisture content, such as swamps, bogs, or other wet environments. In terms of its physical properties, limonite is typically amorphous and lacks crystalline structure, resulting in a dull or earthy appearance. It has a variable hardness ranging from 4 to 5.5 on the Mohs scale and exhibits a yellow, brown, or reddish-brown streak when scratched.
Limonite is an important source of iron due to its high iron content, which can range from 30% to 60%. However, its impurities and variable composition often make it less desirable for direct use in iron production. Despite this, limonite has various industrial applications, including pigments, polishing compounds, and soil amendments. It can also be used as a low-grade iron ore if processed with other methods such as magnetic separation or roasting. Overall, limonite plays a significant role in the Earth's geology and has economic significance due to its iron-rich nature.
A term applied to brown iron ore-so called because allied varieties are found in bogs.

The word "limonite" is derived from the Greek word "leimṓn" (λείμων), which means "meadow" or "meadow pasture". This name was given to the mineral due to its yellowish-brown color, which resembles the color of the meadows. The suffix "-ite" is commonly used in mineral names to indicate that it is a type of mineral.
