The hard hematite ore bodies with > 66 wt% Fe contain microplaty hematite and occur mainly near the contact with the underlying metavolcanic rocks, where they are surrounded by an aureole of hydrothermal carbonate alteration. Relict BIF bedding is generally preserved in the hard ore, with dense hematite alternating with porous hematite.
Hematite, an oxide of iron (Fe 2. 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 mining of hematite was once the state's most developed nonfuel mineral industry, and the occurrence of hematite with nearby deposits of coal (a ...

Hematite is a shiny, dark-colored reddish-brown stone found in South Africa and all over the world. It consists mainly of iron, which gives it its metallic sheen. Hematite stones are opaque, not the strongest of stones (it has a 5-6 on the Mohs hardness scale). And they have a strong metallic luster.
Hematite ore was partially reduced to suboxides in the specified atmospheres. Accorading to the thermodynamic analysis,[14,15] these suboxides contained magnetite and liquid oxide, and the liquid oxide turned to wüstite in the quenching process. The partially reduced ore particles in resin were polished and investigated with an optical microscope.
