Iron Ore Agglomeration Technologies IntechOpen

18-05-2017  Until the 1950s of the last century, the oxidized iron ores that were loaded into the blast furnace had granulometries within 10 and 120 mm. However, the depletion of high-grade iron ore sources has made necessary the utilization of concentration processes with the purpose of enriching the iron ore. Because of these processes, a fine granulometry is produced, and thus iron

Iron is the backbone of the world we have built around us and it is the basic ingredient of steel (iron plus carbon). Iron is a very useful metal because it can be mixed with other metals to make a whole variety of 'alloys' which are even stronger and don't rust easily and can be shaped into products from cars to pins, household appliances to buildings, bridges to railways, food cans to tools.
