    May 18, 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 agglomeration.The active metal has to almost completely corrode before the less active iron or steel begins the process.

Originally thought to be of little value, taconite was considered overburden (waste) in the days when high grade iron ore was mined. The iron content, magnetite, is only 20 30 compared to 50 60 iron content in red ore. Red ore is also referred to as direct shipped ore because it can be shipped without processing.

  • How Is Iron Ore Mined

    Iron is produced by reduction of iron ore, which is often a mixture of oxides, using carbon, carbon monoxide, and hydrogen. While the blast furnace is the dominant reduction process other technologies are emerging which operate on a smaller scale.The iron ore fines that enter the BF need to go through a pelletizing and sintering process. In other cases, such as the smelting reduction (SR) processes that use the fluidized bed technologies the iron ore fines can directly be charged into the reduction process making it highly advantageous.

  • (pdf) Life Cycle Assessment Of Iron Ore Mining And Processing
