Many of the sedimentary iron deposits contain both hematite and magnetite as well as other iron minerals. These are often in intimate association, and the ore is mined, crushed, and processed to recover both minerals. Historically, much of the hematite was not recovered and was sent to tailings piles. More efficient processing today allows more hematite to be recovered from the ore. The tailings can
Hematite is the abundant form of iron oxide, natural red pigment, and an integral part of the largest iron ore deposits on Earth. Highly aesthetic crystals and shiny botryoidal hematite aggregates are also very popular collector specimens.
Throughout the great valley range the deposits of ore are generally found on the slates and sandstones, or between the limestones and overlying or under lying rocks. But when the limestones are stratified horizontally, covering or conceal ing these rocks, the ore is always found in fissures, as represented in figure 173. It would therefore appear that the substance forming these ores is
Large ore bodies of hematite are usually of sedimentary origin; also found in high-grade ore bodies in metamorphic rocks due to contact metasomatism, and occasionally as a sublimate on igneous extrusive rocks ("lavas") as a result of volcanic activity. It is also usually the cause of red soils all over the planet.

30.05.2020· The primary source for hematite is a sedimentary deposit in the Lake Superior district in North America. Other deposits include Brazil (Minas Gerais), Venezuela (Cerro Bolívar) and Canada (Labrador, Quebec). Hematite physically occurs in many forms: specular ore (steel gray color, shiny crystals); micaceous hematite (gray, scaly flakes),
The huge iron ore deposits of Brazil are also well-known to collectors who prize the superb tabular hematite crystals from Brumado, Novo Horizonte, Itabiria, Con Genar de Campo, and Jaguarcu. Bright, lustrous platy crystals sometimes exceeding 5” across are found here. Some crystals are pyramidal, scalenohedral, or rhombohedral.
