CO 2 abatement in the iron and steel industrycokemaking and iron ore preparation are described in Chapter 3. CO 2abatement from the different iron production routes, namely blast furnaces (BFs), direct reduction processes (which produce DRI) and the smelting reduction processes (which eliminate the need for coking and iron ore sinter plants) are covered in the following three chapters.
Iron and Steel Industry | The Canadian Encyclopedia · Canadian iron ores consist mostly of hematite or magnetite, and some siderite and ilmenite. Besides oxides of iron, iron ores contain gangue — minerals such as quartz or fluorite not wanted in iron making. Ores containing proportions of iron of 54 per cent or more are considered highgrade, while those containing lower proportions of iron must be upgraded in order to become .
Seven Iron BrothersThe Seven Iron Men, also known as Merritt Brothers, were ironore pioneers in the Mesabi Range in northeastern Minnesota and the creation of the city that is now known as Mountain Iron. In the late 1800s, the Merritt family founded the largest iron mine in the world and initiated the consolidation of the American railway system into what would ultimately become the United States Steel Corporation.
Taconite Ore ProcessingIron ore concentrates must be coarser than about No. 10 mesh to be acceptable as blast furnace feed without further treatment. Finer concentrates are agglomerated into small "green" pellets, which are classified as either acid pellets or flux pellets. Acid pellets are produced from iron ore and a binder only, and flux pellets are produced by adding between 1 and 10 percent limestone to the ore ...

Ironrich sedimentary rocksIronrich sedimentary rocks are sedimentary rocks which contain 15 wt.% or more, most sedimentary rocks contain iron in varying degrees. The majority of these rocks were deposited during specific geologic time periods: The Precambrian (3800 to 570 million years ago), the early Paleozoic (570 to 410 million years ago), and the middle to late Mesozoic (205 to 66 million years ago).
