Formula: Fe 2 O 3 Hexagonal Description: Hematite is an extremely common mineral. It can form as a sedimentary precipitate, a product of weathering of other iron rich minerals in soils and oxidized zones of ore deposits, as a primary mineral in hydrothermal veins, and as a metamorphic mineral.
Hematite and magnetite are by far the most common types of ore. Pure magnetite contains percent iron, hematite percent, limonite percent, and siderite percent, but, since these minerals never occur alone, the metal content of real ores is lower. Deposits with less than 30 percent iron are commercially unattractive, and, although some ores contain as much as 66 percent iron, there are
Four Kinds of Hematite Ore Dressing Processes. Hematite (Fe2O3) is a kind of weak magnetic mineral, and its crystal belongs to the oxide mineral of hexagonal crystal system. The mineral form is dominated by iron oxide. According to its composition, hematite ore can be divided into four varieties, including ilmenite, aluminum hematite, magnesium

This type of mining is particularly damaging to the environment because strategic minerals are often only available in small concentrations, which increases the amount of ore needed to be mined. Environmental hazards are present during every step of the openpit mining process. Hardrock mining exposes rock that has lain unexposed for geological eras.
A lot of the iron ore found at Mount Whaleback is hematite, which has been the dominant iron ore mined in Australia since the 1960s. Pure hematite contains around 70 percent iron and ranges in color from silver to reddish brown. Iron is extracted from the minerals and commonly used for making steel.
