Magnetite is rock mineral and one of the most important iron ore minerals with chemical formula is iron(II,III) oxide, Fe2+Fe3+2O4 .It also as the name magnetic minerals to attracted to a magnet. It is the most magnetic natural occuring minerals in the World.
The study aimed at investigating the chemical composition and microstructure of raw iron ore from the deposits in Muko area (southwestern 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, also spelled as haematite, is a common iron oxide with the formula Fe 2 O 3 and is widespread in rocks and soils. Hematite crystallizes in the rhombohedral lattice system, and it has the same crystal structure as ilmenite and corundum. Hematite and ilmenite form a complete solid solution at temperatures above 950 °C (1,740 °F).
General Hematite Information : Chemical Formula: ... Composition: Molecular Weight = gm Iron % Fe % Fe 2 O 3 Oxygen % O ... Matto Grosso, Brazil. Mesabi iron ore range, Minnesota, USA. Link to Location Data. Name Origin: From the Greek, haimatites, "bloodlike''" in allusion to vivid red color of the powder. ...
When the ore is melted, it is poured into molds. It cools and forms a scale on the surface that acts as a protective covering for the metal. However, cast iron is naturally prone to rusting because of its high iron composition. When iron comes into contact with oxygen and water vapor, a chemical reaction occurs, and rust is the visible result.
Limonite Iron Ore Description, chemical formula and uses. Jan 28, 2014· Limonite is another ore of iron, this time with a chemical formula of FeO(OH)·nH 2 O, although it can be rather variable in compositions so could have other formulas, and is not considered a true mineral because of the variability of structure and is a mixture of other minerals.

Fe2O3 is the chemical formula for haematite, the ore of iron. Which ore contains both iron and copper? The ore which contains both iron and copper is chalcopyrite.
Increasing iron ore demand, coupled with the depletion of highgrade hematite ores in the United States, after World War II led to development of lowergrade iron ore sources, principally the utilization of magnetite and taconite. Ironore mining methods vary by the type of ore being mined.
"Hematite ore has the chemical formula Fe2O3 and has a very high iron content of 70 percent. . With the chemical formula Fe3O4, magnetite ore has much lower iron content than hematite ore."
Iron has the chemical formula Fe from its Latin name, ferrum. Its atomic number is 26, and its molar mass is grams per mole. It has a metallic gray color and is attracted to magnets.
Hematite is the most important iron ore. The iron content of the pure minerals is as follows: Ankerite is a carbonate of lime, magnesia, manganese, and iron. It is of valuable composition, carries only 14 or 15% of iron, and is used more for its lime and magnesia as a flux than for its ironcontent.
