Limonite - Mining Fundamentals

Limonite is a common iron ore, which forms the coloring matter in different types of soils. It is usually formed from the chemical weathering of iron rich minerals, such as biotite, amphibole, pyroxene, and olivine, the hydration/oxidation of iron rich sulfide minerals, or from the hydration of magnetite and hematite.
