Ore is a deposit in Earth's crust of one or more valuable minerals. The most valuable ore deposits contain metals crucial to industry and trade, like copper, gold, and iron.. Copper ore is mined for a variety of industrial uses. Copper, an excellent conductor of electricity, is used as electrical wire.Copper is also used in construction.
Iron was likely originally discovered and extracted as a result of wood burning on top of iron-containing ores. The carbon within the wood would have reacted with the oxygen in the ore, leaving behind a soft, malleable iron metal. Iron smelting and the use of iron to make tools and weapons began in Mesopotamia (present-day Iraq) between 2700 and 3000 BCE.
What is Iron Ore? Earth's most important iron ore deposits are found in sedimentary rocks. They formed from chemical reactions that combined iron and oxygen in marine and fresh waters. The two most important minerals in these deposits are iron oxides: hematite (Fe 2 O 3) and magnetite (Fe 3 O 4). These iron ores have been mined to produce ...

Iron ores in the form of hematite (ferrous oxide) and magnetite are removed from the earth through mining. The use of heavy mining equipment is necessary to dig out large pits in an area with a large deposit of iron ore; however, because iron does not occur naturally, it is necessary to use a blast furnace to separate or refine iron from the other substances in the iron ore.
The most widely distributed iron-bearing minerals are oxides, and iron ores consist mainly of hematite (Fe 2 O 3), which is red; magnetite (Fe 3 O 4), which is black; limonite or bog-iron ore (2Fe 2 O 3 ·3H 2 O), which is brown; and siderite (FeCO 3), which is pale brown. Hematite and magnetite are by far the most common types of ore.

Extracting iron from iron ore using a Blast Furnace. The common ores of iron are both iron oxides, and these can be reduced to iron by heating them with carbon in the form of coke.
Iron is one of the big 8 elements in the Earth's crust, being the fourth most abundant element at about 5% by weight. Iron ore is abundant, but its isolation is an energy-intensive process. The chief ores are the oxides hematite, Fe 2 O 3, and magnetite, Fe 3 O 4, and its carbonate siderite, FeCO 3.
The principal ores of iron are hematite (ferric oxide, Fe 2 O 3) and limonite (ferric oxide trihydrate, Fe 2 O 3 ·3H 2 O). Other ores include siderite (ferrous carbonate, FeCO 3), taconite (an iron silicate), and magnetite (ferrous-ferric oxide, Fe 3 O 4), which often occurs as a white sand.

Iron content in the DRI is in two forms. One is in metallic form which is known as metallic iron, Fe M, and the second form is iron present in residual iron oxides. The total iron Fe T in DRI is the sum of these two iron components. Metallic iron is the aggregate quantity of iron, either free or combined with carbon (as cementite) present in DRI.
