The iron ores of the Gushan mine occur in the contact zone of a Mesozoic diorite intrusion and are composed primarily of hematite microcrystallites and chalcedony. The hematite microcrystallites have undergone post-mineralization recrystallization and coarsening with resultant formation of lath-shaped hematite porphyroblasts. Microscopic investigation reveals that recrystallization and ...

May 01, 2014 In China, most reserves of rich iron ores have now been depleted and sustainable development of low-grade iron ores has become a critical discussion topic in the mining industry today. The aim of this study was to evaluate the applicability of beneficiating a low-grade, hematite-magnetite ore (assaying 18.64% Fe) for subsequent utilization. In this study, process mineralogy and …

Iron ore is a mineral substance which, when heated in the presence of a reductant, will yield metallic iron (Fe). It almost always consists of iron oxides, the primary forms of which are magnetite (Fe 3 O 4) and hematite (Fe 2 O 3). Iron ore is the source of primary iron for the world's iron and steel industries.

Hematite is one of the most abundant minerals on Earth's surface and in the shallow crust. It is an iron oxide with a chemical composition of Fe 2 O 3. It is a common rock-forming mineral found in sedimentary, metamorphic, and igneous rocks at locations throughout the world. Hematite is the most important ore of iron.
Jul 24, 2008 In sediments, the main mineral phases of iron oxyhydroxides are hematite (αFe 2 O 3), goethite (αFeOOH), lepidocrokite (γFeOOH), maghematite (γFe 2 O 3), magnetite (Fe 3 O 4), and ferrihydrite (5Fe 2 O 3 9H 2 O) (Zhang et al. 2003), which have different magenetic properties (Table 1). Therefore, environmental magnetic studies should be a ...

Jun 04, 2021 Hematite, or haematite, is a dark iron oxide mineral known for its trademark red to red-brown streak and a metallic sheen. As a mineral, hematite is one of our most important iron sources. As a gemstone, it’s just as ubiquitous – hematite is used in everything from masculine and feminine jewelry to carved dice and figurines.
Due to its association with blood and red, hematite may range in color from black and metallic gray to reddish brown in thin spots or hematite crystals. This stone has many uses, but the economic importance of using hematite as iron ore is much greater than its other uses. Its applications such as the production of pigments, preparations for ...

I found this photo on e-bay. The rock was offered for sale as “0.8 lb Meteorite Specimen from Nandan, China!”. The “Buy It Now” price was $295. It looks like a hematite concretion to me. Many hematite concretions start out as masses of cubic pyrite (iron sulfide) crystals that oxidize to hematite (iron oxide). That’s what this one looks.
