Hematite Fe2O3 - PubChem

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 (Fe3O4) and hematite (Fe2O3).

Hematite - Wikipedia

Hematite, also spelled as haematite, is a common iron oxide compound with the formula, Fe2O3 and is widely found in rocks and soils. Hematite crystals belong to the rhombohedral lattice system which is designated the alpha polymorph of Fe 2O 3. It has the same crystal structure as corundum (Al 2O 3) and ilmenite (FeTiO 3). With this it forms a complete solid solution at temperatures above 950 °C (1,740 °F). Hematite naturally occurs in black to steel or silver-gray, brown to reddish-brown, or red colors. It is mined

Hematite - an overview ScienceDirect Topics

Hematite is an ore composed chiefly of a soft micaceous hematite and small amounts of quartz. The micaceous hematite is very thin tablets or leaves of irregular outline, and the quartz is an aggregate of grains. Hematite closely resembles mica schist. Imagine the mica of such a schist replaced by a substance of mica-like thinness and the metallic luster of polished iron for a good idea of how ...

The Crystal Structures of Corundum and Hematite

07/01/2010  Hematite comes in many varieties, each having their own unique name and composition. Hematite is an iron oxide, and very important as an ore of iron. It is also used as a pigment and is collected as a mineral specimen. It is blood red in powdered form, but can be gray, black, red or brown in its solid form. It is also used in jewelry, either as a set stone, or as a piece itself.

The study aimed at investigating the chemical composition and microstructure of raw iron ore from the deposits in Muko area (south-western Uganda). The quality of this iron ore was evaluated to establish its suitability to serve as a raw material for iron production. Samples were taken from the six hills of Muko ore deposits and tests carried out to establish their composition and properties.

Hematite — Google Arts Culture

Hematite varieties include kidney ore, martite, iron rose and specularite. While these forms vary, they all have a rust-red streak. Hematite is not only harder than pure iron, but also much more brittle. Maghemite is a polymorph of hematite with the same chemical formula, but with a spinel structure like magnetite.
