O 3), is also known as "red iron ore" and in 1967 was designated as the State Mineral by the Alabama Legislature.Hematite was mined for many years in the Valley and Ridge area of central and northeastern Alabama. The micaceous hematite is very thin tablets or leaves of irregular outline, and the quartz is an aggregate of grains. The new oxygen immediately combined with the iron to form hematite, which sank to the bottom of the seafloor and became the rock units that we know today as the banded iron formations. It can also form during contact metamorphism when hot magmas react with adjacent rocks. Hematite ore is simply mined, crushed, and after that screened into either lump or fines. The two most important minerals in these deposits are iron oxides: hematite (Fe 2 O 3) and magnetite (Fe 3 O 4). Hematite, also spelled as hamatite, is the mineral form of iron(III) oxide (Fe2O3), one of several iron oxides. It is an iron oxide with a chemical composition of Fe2O3. The bright silver color of hematite and its "weighty feel" make it a very popular tumbled stone. Majority of it is mined from banded iron formations like the sample above from Kryvyi Rih, Ukraine.
