Limonite: an iron oxide used as pigment and iron ore

Limonite has been used as a lowquality iron ore for thousands of years. Commercial mining of limonite as a source of iron is no longer done in areas where reasonable deposits of hematite and magnetite are present or readily imported. Limonite deposits are usually too small and too impure for use in

Goethite an overview ScienceDirect Topics

12.17.6 Iron Ores. Iron ore minerals such as goethite (FeO(OH)) and hematite (Fe 2 O 3) are floated by amine, oleate, sulfonate, or sulfate collectors. Processing involves preconcentration by gravity or magnetic separation, followed by flotation. Iron ore flotation has increased in importance due to market requirements for higher grade products.

Limonite Wikipedia

While the first iron ore was likely meteoric iron, and hematite was far easier to smelt, in Africa, where the first evidence of iron metallurgy occurs, limonite is the most prevalent iron ore. Before smelting, as the ore was heated and the water driven off, more and more of the limonite was converted to hematite.
