Keywords: Reduction, iron oxide, hydrogen, mechanisms, kinetics, thermobalance. Abstract To reduce the emission of greenhouse gases by the steel industry, particularly for ironmaking, the production of DRI (Direct Reduced Iron) using hydrogen as the reducing gas instead of carbon monoxide is being considered.
Coal is gassified to a lean reducing gas, containing carbon monoxide and hydrogen. This gas reacts with iron oxides (haematite Fe 2 O 3, magnetite Fe 3 O 4, wuestite FeO) to produce a reduced form of iron oxide (wuestite FeO, iron Fe). The reduced iron oxide is re-oxidised with steam to form magnetite and hydrogen.

METHOD OF CONVERTING I-IEMATITE TO been reduced from hematite to magnetite. or.003 conveyed out of the furnace in the gas stream. after the ore has been reduced to the method of this invention. may be cooled and the dust separated as burner is regulated so that the ?ame has the desired'' 70 before.
Industrial iron production starts with iron ores, principally hematite, which has a nominal formula Fe 2 O 3, and magnetite, with the formula Fe 3 O 4. These ores are reduced to the metal in a carbothermic reaction, i.e. by treatment with carbon. The conversion is typically conducted in a blast furnace at temperatures of about 2000 °C.
If theoriginal ore is too iron rich, the furnace won''t produce the glass slaguntil the iron has been heated past its melting point, producing castiron. If the furnace is too cool, or there isn''t enough iron, the ironwill act as a flux and the bloom will be mostly glass.

We have traded iron oxide ore domestically for over 10 years and in 2009/10 took ownership of our first of three mining properties. These assets allow for controlled, scalable production of iron oxide ore, initially through reclamation and processing of high-quality, low-moisture sinter fines.
Production and Distribution of Iron Ore in India! Iron ore is a metal of universal use. It is the backbone of modern civilisation. It is the foundation of our basic industry and is used all over the world. The standard of living of the people of a country is judged by the consumption of iron. Iron ...
Iron Ore Iron ores are rocks and mineral deposits from which clanging iron can be reasonably extracted The ores are generally prosperous in iron oxides and fluctuate in color ranging from dark grey, bright yellow, deep purple, to even rusty red The iron by its own is usually found in the structure of magnetite (Fe3O4),
Since sulfur and phosphorus bond with iron in the reduction of iron oxides, iron and magnetite can be separated from iron sulfides and phosphides using difference in the Curie points for different iron compounds and magnetic separation at ~500 °C. The possibility to create high-temperature magnetic separators for fine materials is pointed .
When the objective minerals are achieved, they contain much moisture. The dry iron concentrate is achieved by the thickening and drying. At present, the domestic magnetite ore beneficiation processing line is mainly used to beneficiate the low grade "Anshan style" magnetite ore.
"Peg Leg Magnetite Mine" is a past producer deposit site discovered in 1692 in the Appalachian Highlands of Tennessee, The United States. It is a deposit, located in the Cranberry Magnetite District mining district and is not considered to be of world-class significance. 1 Iron deposits are documented at "Peg Leg Magnetite Mine."

Australia''s iron ore reserves and resources are in both hematite and magnetite ores. Because of the high average grades (% Fe) of hematite ores when compared to the average grades for magnetite ores, it is necessary to report national resources in terms of contained iron.
This paper, as a preliminary study of the innovative process, mainly describes the process of low-temperature hydrogen reduction of hematite ore and magnetic separation of the resulting magnetite ore, since hydrogen, which is the main component of COG, is an efficient reducing agent.
