Iron oreEdit. Iron ore is rock containing enough iron content, and in sufficient volume and accessibility to mining and transportation to be able to be economically mined. Iron in ore iron is most commonly found in the form of magnetite (Fe3O4), hematite (Fe2O3), goethite (FeO(OH)), limonite (FeO(OH)·n(H2O)) or siderite (FeCO3).

Limonite is a mineral of iron ore and represents a small percentage of extracted iron. It is crystalline to amorphous, has a hardness of 1 to, SG to 4, and is yellowish, brown or black. It is the result of the decomposition of iron minerals, where water, carbon dioxide, acid humus and oxygen react with minerals and little by little to transform them into limonite.
Hundreds of fine, glassy Hemimorphite crystals on a matrix of Limonite. Named Hemimorphite because of the hemimorph development of its crystals. This unusual form, which is typical of only a few minerals, means that the crystals are terminated by dissimilar faces.
Iron ores are rocks and mineral deposits from which clanging iron can be reasonably extracted. Iron ore mining is classified into two categories manual mining and mechanized mining methods. Haematite and magnetite are the most commonly found iron ore minerals. Deposits of iron ore such as haematite containing iron oxide are found in sedimentary rocks from which the oxygen is removed from the ...
