Hematite is the primary ore of iron, and thus massive amounts of hematite are mined for their iron content. People have used it throughout the world and throughout history as a source of red pigment or paint in its powdered form. Some forms of polished and rock-tumbled hematite have a silvery appearance this form of hematite has been a popular ...

Ore is most often found in the form of hematite and magnetite, though goethite, limonite and siderite types are also common. Approximately 98 percent of the iron ore produced in the world is used to make steel. Hematite. Hematite ore has the chemical formula Fe2O3
Hematite iron ore is a very common mineral on Earth and it also occurs everywhere on the planet Mars where it is responsible for the planets distinctive red color. It was first identified on Mars by the Thermal Emission Spectrometer TES, aboard Mars Global Surveyor.
The lenticular ore bodies are 2.0-3.5 m thick and 10 to 100 m long. The entire mineralized zone streches NE-SW with a dip of 25-45176 to the NW. The ore bodies consist of the alternations of very thin 0.03-0.8 mm to 5 cm magnetite-hematite beds, separated by sharp boundaries of the thicker gangue-bearing beds. Hematite is cryptocrystalline or

Types of Iron Ore Hematite vs. Magnetite . Types of iron ore Magnetite. With the chemical formula Fe3O4, magnetite ore has much lower iron content than hematite ore. That means it has to be concentrated before it can be used to produce steel. However, the ores magnetic properties help separate magnetite ore from rock during concentration.
Hematite and ilmenite form a complete solid solution at temperatures above 950 176C. Hematite is a mineral, colored black to steel or silver-gray, brown to reddish brown, or red. It is mined as the main ore of iron. Varieties include kidney ore, martite pseudomorphs after magnetite, iron rose and specularite specular hematite.
