Apr 25, 2017· Magnetite is composed of 72% iron, Hematite is 70% iron, Goethite is 63% iron, and Limonite is 60% iron. Leading Iron Ore Producing Countries. Much of the iron ore are in the sedimentary rocks called Banded Iron Formations (BIFs), which dates back to more than 542 million years.
Goethite can also occur in stalactitic or massive forms and in tufts and drusy coatings. Goethite is an iron oxide hydroxide, although manganese can substitute for up to 5 percent of the iron. It forms as a weathering product in the oxidation zones of veins of iron minerals, such .
Hematite is solid material with no internal structure visible and Goethite has the inner needle-like structure. So if you look at broken surfaces and can see the inner close packed striated structure Goethite is the mineral. Goethite can also be tiny yellow to brown needles, standing on their own. Rolf

Hematite concretions form by precipitation of iron oxide from iron rich solutions. Hematite nodules are often formed in sedimentary rocks by oxidation of pyrite or marcasite (iron sulfide) crystals. Concretions and nodules, which may also be composed in part of the iron oxy-hydroxides, limonite and goethite, come in a wide variety of bizarre ...
