Hematite - Wikipedia

Hematite (/ ˈ h iː m ə ˌ t aɪ t, ˈ h ɛ m ə-/), also spelled as haematite, is a common iron oxide compound with the formula, Fe 2 O 3 and is widely found in rocks and soils. Hematite crystals belong to the rhombohedral lattice system which is designated the alpha polymorph of Fe 2 O 3.It has the same crystal structure as corundum (Al 2 O 3) and ilmenite (FeTiO 3).

Opportunity Puts Hematite on Hold - Astrobiology Magazine

05/02/2004· Hematite, an iron-bearing mineral, typically forms in the presence of water. By studying the distribution of hematite and determining what other minerals are found along with it, MER scientists hope to understand the role that water played in the history of Meridiani Planum. The detection of hematite from orbit is what initially interested planetary geologists in Meridiani as a landing site ...

Iron ore (fines) - Cargo Handbook - the world's largest ...

Ores carrying very high quantities of hematite or magnetite (greater than ~60% iron) are known as "natural ore" or "direct shipping ore", meaning they can be fed directly into iron-making blast furnaces. Most reserves of such ore have now been depleted. Iron ore is the raw material used to make Pig Iron, which is one of the main raw materials to make steel. 98% of the mined iron ore is used to ...

This model requires ferrous iron to be released from minerals and transported in solution via groundwater, possibly with the required reducing conditions being produced by CH 4 or other hydrocarbons (4, 8) or possibly by reduced sulfur species such as H 2 S . However, this model cannot fully explain why spherical Fe-oxide–encrusted concretions were formed.
