What is the difference between hematite and limonite?
Hematite and limonite are common types of iron ores and they have some distinct differences in chemical composition, color and uses. The following will describe the differences between hematite and limonite.
Chemical composition:
Hematite is chemically composed of ferrous oxide (Fe2O3), which consists of iron and oxygen elements. The chemical composition of limonite is hydrated iron oxide, and the main component is hydrated ferrous oxide (FeO(OH)-nH2O). There are significant differences between the two in terms of chemical composition.
Color:
Hematite appears red, brownish red or black. This color is due to its ferrous oxide composition. Limonite usually has a brown or yellowish-brown color due to the presence of hydrated ferrous oxide in it.
Iron content:
Hematite has a high iron content, usually above 60%, and some high grade hematite can even reach over 70%. Limonite, on the other hand, has a lower iron content, generally between 30% and 40%.
Uses:
Hematite is one of the most important iron ores and is widely used in the smelting of iron and in the manufacture of steel due to its high iron content. Hematite is also used in the production of ferroalloys and in the manufacture of ore pigments. Limonite has a lower iron content and is mainly used in the production of ferroalloys and dyes.
Hematite ore is mostly authomorphic or semi-authomorphic crystalline metamorphic structure, followed by wrapped metamorphic structure, squamous metamorphic structure, fused structure, accountable and accountable residual structure, crushed structure, etc. The striped structure is the main structure, followed by the wrinkled and dense massive structure.
The ores of limonite deposits such as iron pit limonite are colloidal, concentric ring, crystalline shelf, reticulated accountable remnant and granular structure, commonly sparse earthy honeycomb, dense massive, lattice and breccia structure, etc. For example, the structure of Dabaoshan iron cap limonite has account pseudomorphic, account residue, thistle-like, granodiorite and silt-like structures.
The ore structure is colloidal, honeycomb, spongy, laminated-striped, brecciated, porous, grape-like, and lattice-like Daxigou type limonite ore structure is mainly remnant sandy, scaly, and granite metamorphic structure.
The ore structure is mainly striped, followed by loose earthy, crusty, stalactitic and wrinkled structures. Dense and dipping structures.
The structure of the ore of the hematite deposit is maize and granular, and the structure is maize, bean, kidney and laminated. There are also semi-automorphic and other-shaped granular structures, and the structure is striped, blocky and laminated.
