  • Goethite Uses Crystal Benefits

    2010-12-30· In the form of stalactitic formations, oolites, and concretions, it can be located all over the surface of the Earth. Goethite was named after Johann Wolfgang von Goethe, a mineralogy enthusiast. It is one of the most stable iron oxides, thermodynamically, at ambient temperatures, and as a result, it is considered as either the first oxide to be created, or the end oxide for many changes.

    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.

  • Antimony Sorption to Goethite: Effects of Fe(II)-Catalyzed

    The environmental mobility and bioavailability of antimony (Sb) are strongly influenced by sorption to Fe(III) oxide minerals, such as goethite (αFeOOH). Exposure to aqueous Fe(II), as occurs, for example, under reducing conditions in soils and sediments, catalyzes the recrystallization of goethite. Herein, we examine, for the first time, the effect of Fe(II)-catalyzed goethite
