Goethite Weathering Product Ore Iron
Goethite 3+O(OH)
Occurrence: A common weathering product derived from numerous ironbearing minerals in oxygenated environments; an important component of ore in weathered iron deposits. Also a primary precipitate in hydrothermal, marine, and bog environments upon oxidation of reduced iron .
Goethite
Goethite is a common weathering product of ironbearing minerals like magnetite, pyrite and siderite. It is an oxyhydroxide or iron — FeO(OH). The most characteristic feature of this mineral is brown to yellowish color. It may resemble hematite (Fe 2 O 3), but hematite is either gray or reddish. It changes to hematite on dehydration.

Introduction: goethite is a common weathering product of ironbearing minerals in oxygenated environments and can be an important component of iron ore derived from weathered iron mineralization. Goethite is also a primary precipitate in hydrothermal, marine, and bog environments upon oxidation of reduced ironbearing waters.
GOETHITE
Goethite is a widespread mineral in the iron ranges of the Northern Peninsula, and as an alteration product of ironbearing minerals in rocks throughout the state. Goethite typically forms under supergene oxidizing environments by weathering of iron oxides, sulfides, carbonates, and silies. It is also a

Labrador West Property, Labrador
Based on drilling to date, the deposit presents a mix of weakly to strongly weathered and commonly banded quartz(+/silie, carbonate)hematitegoethite + manganese oxide, limonite and locally magnetite mineralization. Goethite is a secondary product formed during chemical weathering and replaces both hematite and magnetite.

01/11/2003 · Goethite is one of the most common minerals and is typically formed under oxidising conditions as a weathering product of ironbearing minerals (Klein and Hurlbut, 1985). It has a multitude of shapes and sizes but occurs commonly with a basic acicular morphology ( Cornell and Schwertmann, 1996 ).

The hematite ore is bluegrey, massive to porous and mostly microplaty. Goethite associated with the hematite is dense, while massive, vitreous and porous cellular types are found closer to the surface. The amount of geothite decreases with depth and the hematite becomes more porous suggesting the goethite is a Tertiary weathering product.
