Hematite A primary ore of iron and a pigment mineral Geology Learn about the uses and properties of the mineral hematite. Australia, Brazil, India, Russia, Ukraine, South Africa, Canada, Venezuela, and the United States.
Other important deposits include Quebec and Labrador in Canada, Minas Gerais in Brazil, and Cerro Bol237;var in Venezuela. Properties of Hematite. Hematite occurs in different forms and has separate names. The coarse grained crystals of hematite, with a steel gray color and metallic luster, are known as specular iron ore. Thin scaly ores are known as micaceous hematite.
Approximately 98 percent of the iron ore mined is used to make steel. The method used to mine the ore is determined by the type of ore being mined. The four types of ore deposits most commonly being mined are magnetite, titanomagnetite, massive hematite, and pisolitic ironstone deposits.
The FLOTIGAM174; series includes ether amines, used for hematite iron ore, and ether diamines, used for magnetite iron ore. The FLOTIGAM series collectors are able to produce iron ore with low silica content by froth flotation resulting in high purity concentrate, which is needed for steel production.

Jan 18, 20060183;32;Therefore, all sources of iron used by human industry exploit iron oxide minerals, the primary form which is used in industry being hematite. However, in some situations, more inferior iron ore sources have been used by industrialised societies when access to high grade hematite ore
Hematite, also spelled haematite, heavy and relatively hard oxide mineral, ferric oxide (Fe 2 O 3), that constitutes the most important iron ore because of its high iron content (70 percent) and its abundance.
Iron ore is the raw material used to make Pig Iron, which is one of the main raw materials to make steel. 98% of the mined iron ore is used to make steel. Indeed, it has been argued that iron ore is quot;more integral to the global economy than any other commodity, except perhaps oilquot;. Iron ore is mined in about 50 countries.

Cerro Bol237;var is thought to contain more than 250,000,000 tons of high grade ore, a mixture of hematite, limonite, and a small percentage of magnetite, with an average of more than 50 percent iron. The ore is mined year round by open cut methods and sent by rail to Puerto Ordaz 90 mi (120 km) to the northeast at the confluence of the Caron237;
Most ore is now produced in China, Australia, Brazil, India, Russia, Ukraine, South Africa, Canada, Venezuela, and the United States. Hematite has a wide variety of other uses, but their economic significance is very small compared to the importance of iron ore.

Hematite is the most important iron ore. The iron content of the pure minerals is as follows Ankerite is a carbonate of lime, magnesia, manganese, and iron. It is of valuable composition, carries only 14 or 15% of iron, and is used more for its lime and magnesia as a flux than for its iron content.

Hematite Iron Ore Iron Ore. Hematite Iron Ore. Posted on January 25, 2014 by ironore. There are several types of iron ore. The most commonly mined type is Hematite, particularly in Brazil, China and Australia, where it makes up 96% of all exports.
Hematite is the principle ore of iron. Huge quantities are mined throughout the world for industrial production. Huge quantities are mined throughout the world for industrial production. It is the source for roughly 90 percent of all iron mined in the United States.
Hematite crystallizes in the rhombohedral lattice system, and it has the same crystal structure as ilmenite and corundum. Hematite and ilmenite form a complete solid solution at temperatures above 950 176;C (1,740 176;F). Hematite is colored black to steel or silver gray, brown to reddish brown, or red. It is mined as the main ore of iron.
Currently magnetite iron ore is mined in Minnesota and Michigan in the U.S., and Eastern Canada mine taconite. Magnetite bearing banded iron formation is currently mined extensively in Brazil, which exports significant quantities to Asia, and there is a large and developing magnetite iron ore industry in Australia.
