Hematite noun. An important ore of iron, the sesquioxide, so called because of the red color of the powder. It occurs in splendent rhombohedral crystals, and in massive and earthy forms; - the last called red ocher. Called also specular iron, oligist iron, rhombohedral iron ore, and bloodstone. See Brown hematite, under Brown.

Iron Ores (Hematite and Magnetite) Iron is a metal from the periodic table's first transition series and group 8. It is the most common element on Earth by mass, just ahead of oxygen (32.1 % and 30.1 %, respectively), forming much of the Earth's outer and inner cores. It is the fourth most abundant element in the crust of the Earth.
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.

As a adjective iron is (not comparable) made of the metal iron. As a verb iron is
Difference Between Iron Ore and Iron. • Iron, which is one of the most useful metallic elements, is not found independently but in the form of its oxides under the surface of the earth. • These oxides are called iron ores and are found in many igneous rocks. • Oxygen is removed from iron ores to make use of iron.
Hematite is a mineral that contains iron in the form of Fe 2 O 3. The primary distinction between magnetite and hematite is that magnetite is ferromagnetic and hematite is paramagnetic. Magnetite Magnetite is an iron ore that contains iron in the form of Fe 3 O 4.
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.
Iron formation consists of iron ore such as siderite, magnetite, and hematite, with silica in the form of chert, jasper, etc., generally in bands, but sometimes not distinctly so. The bands of iron ore are at times high-grade, but are often mixed with a good deal of silica, the whole making an ore too lean for use without concentration.
