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.
The worlds resources are dominated by low-grade ore, though current world production of iron ore is largely by supply from deposits of high-grade ore composed of either rocks of massive hematite or pisolitic goethite. World iron ore production in 2013 was 2.95 billion tonne, with the major producers being China, Australia, and Brazil.
Apr 03, 2015 Understanding Iron Ores and Mining of Iron Ore. Iron Fe is an abundant and a widely distributed element in the in the crust of the earth, constituting on an average ranging from 2 to 3 in sedimentary rocks to 8.5 in basalt and gabbro. Its supply is
Iron ore is mined, crushed and separated into lump and fines components, which are sold as separate products. Quality and therefore value depends upon the shipped composition of each product matching a target composition vector, in iron and in several other minerals. Each day, ore is selected for mining to meet these target grades.

Iron is the cheapest and one of the most abundant of all metals, comprising nearly 5.6 of the earths crust and nearly all of the earths core. Iron is primarily obtained from the minerals hematite Fe 2 O 3 and magnetite Fe 3 O 4 . The minerals taconite, limonite FeO OH nH 2 O and siderite FeCO 3 are other important sources.
2.1 Iron Ore Composition Iron very rarely occurs in the earths surface as a metal. It is widely distributed, combined with oxygen as iron oxides. In fact it is believed that iron makes up about 5 by weight of the earths crust. Geologists recognise various types of iron ore, classified chiefly according to iron Fe content see Table 1 below.

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 almost every iron and ...
Because iron ore always has bands of other minerals intermingled in the deposit and the ore itself is made up of iron and non-iron minerals, the composition of the tailings varies considerably between mines and even over time within the same mine.

Jan 12, 2020 History . 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.
