    Pig iron is commonly mistaken for meteorites, and although this slag is metallic, heavy, and resembles meteorites, it is just a byproduct of a past mining industry Eastern Kentucky Several iron mines operated in Bath and Menifee Counties, producing an oolitic hematite ore from Silurian rocks called the Rose Run and Preston iron ore banksIron ores are rocks and mineral deposits from which clanging iron can be reasonably extracted Iron ore mining is classified into two categories manual mining and mechanized mining methods Haematite and magnetite are the most commonly found iron ore minerals Deposits of iron ore such as haematite containing iron oxide are found in sedimentary rocks from which the oxygen is removed from theIron Ore Mining Techniques, Metal Extraction, Types of

  • Ancient iron production

    Ancient iron production refers to iron working in times from prehistory to the early Middle Ages where knowledge of production processes is derived from archaeological investigation Slag, the byproduct of ironworking processes such as smelting or smithing, is left at the ironworking site rather than being moved away with the productIt also weathers well and hence it is readily availableIron 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 industriesIron Ore Statistics and Information USGS
