  • Iron Ore: From Mining to Processing to Dust Control

    Iron ore is a rock or mineral from which metallic iron can be extracted economically It constitutes 5% of the earth’s crust Viable forms of ore contain between 25% and 60% iron Ore greater than 60% iron is known as natural ore or direct shipping ore, meaning it can be fed directly into ironmaking blast furnacesIron Mining Process From blasting to crushing to separation – more than 85% of the iron mined in the United States is mined in northeastern Minnesota to make our nation’s steel Blasting Taconite is a very hard rock Using explosives, theIron Mining Process Minnesota IronIron ore is the key raw material for steel production enterprises Generally, iron ore with a grade of less than 50% needs to be processed before smelting andIron Ore Processing Prominer (Shanghai)

  • Processes and Procedures in the Extraction of Iron

    The extraction of iron from its ores is quite a technical process The iron ore is first roasted in air to produce iron(III) oxide which is mixed with coke and limestone and then further heated to a very high temperature in a blast furnace These materials are loaded into the blast furnace from the top while a blast of hot air is introduced into it from beneath via small pipes411 Iron Ore Mining There are two basic methods of mining iron ore These are: • Surface mining or openpit mining • Underground or shaft mining To be competitive, iron mining must be done on a very large scale Surface mining is the preferred choice, although there are exceptions Small, lowcapacity mines have rapidly disappearedEnergy and Environmental Profile of the US MiningThe iron and steel manufacturing process begins with mining raw materials, which must then be carefully processed to ensure quality finished products that meet specificationsThere are more than 3,500 different grades of steel with many different physical, chemical, and environmental propertiesRaw Material Mining and Quality Control for Steel
