Goethite specific gravity
WebIt has a specific gravity ranging from 4.9 to 5.3. Limonite (FeO(OH)·nH2O): Limonite is a yellowish-brown iron ore mineral that forms as a result of weathering and hydration of other iron-bearing minerals, such as hematite and magnetite. Limonite is typically amorphous or earthy in texture, and it often contains goethite (FeO(OH)) as an impurity. 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 ironstone" ) but is more typically massive. … See more Goethite is a mineral of the diaspore group, consisting of iron(III) oxide-hydroxide, specifically the "α" polymorph. It is found in soil and other low-temperature environments such as sediment. Goethite has been well … See more Goethite is found all over the planet, usually in the form of concretions, stalactitic formations, oolites (a form consisting of tiny round grains cemented together), reniform (kidney shapes) or … See more • Iridescent goethite, Filón Sur Mine, Tharsis, Huelva, Spain • Goethite from Minas Gerais, Brazil See more • Spencer, Leonard James (1911).
