Iron mining

The iron industry has slowly matured within the Lake Counties for centuries with industrial growth spreading from the small bloomery and forge sites coastal plateau workings and the narrow veins of the fells to the huge mining and iron smelting complexes of the late 19th and 20th centuries The story of iron ore mining in West Cumbria

From ore to steel – ArcelorMittal

Fine-grained iron ore is processed into coarse-grained clumps for use in the blast furnace Coal is cleaned of impurities in a coke furnace yielding an almost pure form of carbon A mixture of iron ore and coal is then heated in a blast furnace to produce molten iron or pig iron from which steel is made

How iron is made

Iron ores are mainly iron oxides and include magnetite hematite limonite and many other rocks The iron content of these ores ranges from 70% down to 20% or less Coke is a substance made by heating coal until it becomes almost pure carbon Sinter is made of lesser grade finely divided iron ore which is roasted with coke and lime to remove

Iron Ore Statistics and Information

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 world's iron and steel industries
