Goethite: The mineral goethite information and pictures

Goethite is a common mineral, and is a frequent matrix material for other more aesthetic minerals. It is usually a dark, uninteresting mineral, though specimens from a handful of locations (especially Colorado) are remarkable for their delicate and beautiful crystal growths and velvety botryoidal growths. Goethite is also frequent as black crystal sprays that form within geodes on drusy Quartz.Онлайн-запрос

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.
