Iron(III) oxide Wikipedia

Iron(III) oxide or ferric oxide is the inorganic compound with the formula Fe 2 O 3.It is one of the three main oxides of iron, the other two being iron(II) oxide (FeO), which is rare; and iron(II,III) oxide (Fe 3 O 4), which also occurs naturally as the mineral magnetite.As the mineral known as hematite, Fe 2 O 3 is the main source of iron for the steel industry.get price

Laterite Wikipedia

Laterite is a soil and rock type rich in iron and aluminium and is commonly considered to have formed in hot and wet tropical areas. Nearly all laterites are of rusty-red coloration, because of high iron oxide content. They develop by intensive and prolonged weathering of the underlying parent rock.Tropical weathering (laterization) is a prolonged process of chemical weathering which producesget price

Iron(III) Oxide Encyclopedia

Iron(III) OxideOVERVIEWIron(III) oxide (EYE-urn three OK-side) is a dense, reddish-brown, crystalline compound that usually occurs as lumps or a powder. It occurs in nature as the mineral hematite and is a component of the rust that forms on objects made out of iron that are exposed to the air. Rust itself is actually a complex mixture of iron oxides and hydroxides, including Fe2O3, FeO, Fe3O4get price

Use of red ochre by early Neandertals PNAS

The use of manganese and iron oxides by late Neandertals is well documented in Europe, especially for the period 60–40 kya.
