Goethite - Wikipedia

2019-11-03  Composition. Goethite is an iron oxyhydroxide containing ferric iron. It is the main component of rust and bog iron ore. Goethite's hardness ranges from 5.0 to 5.5 on the Mohs Scale, and its specific gravity varies from 3.3 to 4.3. The mineral forms prismatic needle-like crystals ("needle iron ore") but is more typically massive.

Bench-scale calcination and sintering of a goethite iron

In Brazil, iron ore with a high grade of goethite (FeOOH) (LOI > 3.5%), independent of its Fe grade, is considered marginal because goethite causes excessive mud generation in the wet processing step, which is very harmful in flotation (slime coating phenomena) and filtration (blinding) operations.
