Metallic Iron is most commonly produced from the smelting of iron ore to produce pig iron. Iron ore is in the form of rock and vary in color from dark grey to rusty red and is usually found in the form of magnetite (Fe3O4), hematite (Fe2O3) which is also called "natural ore", limonite or siderite. Siderite is a mineral composed of Iron carbonate FeCO3.
iron ore mining hematite:Iron ore is a mineral substance which when heated in the presence of a reductant will yield metallic iron Fe It almost always consists of iron oxides the primary forms of which are magnetite Fe 3 O 4 and hematite Fe 2 O 3 Iron ore is the source of primary iron for the worlds iron and steel industries.

Magnetite ore, long the leading source of domestic iron supply in North America, Europe and China, is now increasingly relevant across the globe. The perception that magnetite ore is an inferior substitute to hematite ore is now firmly changing. As easily accessibly, economic hematite deposits become rarer, magnetite ore will continue to emerge as an [.]
Hematite is a very common iron oxide mineral (Fe2O3) that is found in rocks throughout the world. It is the most commonlymined ore of iron. The steel used to make your car, furniture and even the nails in your home was probably made from iron produced by mining hematite.
Types of Iron Ore: Hematite vs Magnetite, Types of iron ore:, processing magnetite ores result in a significantly higher carbon footprint than with the . Live Chat; highgrade hematite iron ore deposit Magnetite is an iron oxide mineral, processing hematite and magnetite .
Other minerals, such as magnetite, contain higher concentrations of iron, but hematite is so much more abundant that it is the most economically important iron ore. In North America, over 90% of our iron comes from hematite deposits and without hematite our steelbased society could not exist.
Magnetite is a major source of iron. Banded iron formations are precambrian metasedimentary rocks where the ironbearing phase is usually either magnetite or hematite. Very rich magnetitic iron ore is in Kiruna (northern Sweden) although the formation details are not clear (it is not banded iron formation).
Algomatype BIFs are also finely layered intercalations of silica and an iron mineral, generally hematite or magnetite, but the individual layers lack the lateral continuity of Lake Superiortype BIFs. Algomatype BIFs are found within rock sequences containing a significant proportion of submarine volcanic rocks,...

The most widely distributed ironbearing minerals are oxides, and iron ores consist mainly of hematite (Fe2O3), which is red; magnetite (Fe3O4), which is black; limonite or bogiron ore (2Fe2O3·3H2O), which is brown; and siderite (FeCO3), which is pale brown. Hematite and .
The most common ores of iron are hematite Fe 2 O 3, and magnetite, Fe 3 O 4. These ores can extract iron by heating them with the carbon present in the coke. Heating coal in the absence of air produces coke. Coke is cheap and acts as the heat source and is also the reducing agent for the reaction.

The Carajas Mine in Brazil, meanwhile, is the largest known iron ore mine in the world, and is managed by the Vale Company In Asia, China also has some major iron ore reserves, including the hematite ore deposits at TungYehChen and Dongye. Types of Iron Ore: Hematite vs Magnetite | Investing News,
Jun 14, 2011· There are many ores of iron found underneath earth and they are known as siderite, magnetite, hematite and limonite. All these are oxides of iron with some more elements associated in small quantities (mostly silicates). As iron ores are oxides, refinement of the ore to remove oxygen is necessary before we can expect to get pure iron.

Magnetite: Mineral information, data and localities. JacobsiteMagnetite Series. MagnesioferriteMagnetite Series. Magnetite is an important iron ore, along with hematite.
Uses of Hematite (Iron Ore) Hematite is the world's most important ore of iron. Although magnetite contains a higher percentage of iron and is easier to process, hematite is the leading ore because it is more abundant and present in deposits in many parts of the world. Hematite is mined in some of the largest mines in the world.
