Hematite (iron ore) weighs gram per cubic centimeter or 5 150 kilogram per cubic meter, density of hematite (iron ore) is equal to 5 150 kg/m³. In Imperial or US customary measurement system, the density is equal to pound per cubic foot [lb/ft³], or .
When the iron grade is too low to transport the ore, the ore must be agglomerated which demands a considerable amount of energy (1,500 MJ/ton of ore during pelletisation [8]). Because the energy demand depends on the iron grade, a magnetite with an iron content of 72 % can be compared to a hematite with an iron content of 62 %.

Hematite, also spelled as haematite, is a common iron oxide with a formula of Fe 2 O 3 and is widespread in rocks and soils. Hematite forms in the shape of crystals through the rhombohedral lattice system, and it has the same crystal structure as ilmenite and and ilmenite form a complete solid solution at temperatures above 950 °C (1,740 °F).
Limonite (/ ˈ l aɪ m ə n aɪ t /) is an iron ore consisting of a mixture of hydrated iron(III) oxidehydroxides in varying composition. The generic formula is frequently written as FeO(OH)· n H 2 O, although this is not entirely accurate as the ratio of oxide to hydroxide can vary quite widely. Limonite is one of the three principal iron ores, the others being hematite and magnetite, and ...

Found down under in Australia, this iron ore consists of iron oxide, which gives it its powerful grounding properties. To access the healing properties of Hematite, create a sacred healing space by clearing the room of todo lists, cell phones, and anything else that could cause a distraction.
Hematite ore makes up the bulk of Australia''s iron ore production and of the global seaborne trade in iron ore. Highgrade hematite which can be shipped directly to customers after simple processing (crushing, screening, sorting and blending) is often referred to as ''Direct Shipping Ore'' or DSO.
Iron Oxides—Fe 2 O 3. Hematite /Itabirite—Research and actual field use has shown hematite to be an excellent alternative to barite. 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, an oxide of iron (Fe2O3), is also known as "red iron ore" and in 1967 was designated as the State Mineral by the Alabama Legislature with Act no. 503 . Approximately 375 million tons of hematite was mined in Alabama from 1840 to 1975 (when mining in Alabama ceased), contributing to the development of Birmingham as an industrial center.
Hematite is extremely dense and heavy. The iron concentration in hematite is extremely high, making it the most important source of iron ore. It also has a very high refractive index (), which is much higher than even diamonds () and moissanite (). This is what gives the stone its unique, metallic luster.
