Sintering: A Step Between Mining Iron Ore and Steelmaking

World resources are estimated to be greater than 800 billion tons of crude ore containing more than 230 billion tons of iron. The only source of primary iron is iron ore, but before all that iron ore can be turned into steel, it must go through the sintering process. Sinter is the primary feed material for making iron and steel in a blast furnace.

What Is Iron Ore Sintering? (with pictures)

06/12/2020  Mining operations pull raw ore from the earth’s crust, separating it into high-grade and low-grade, based on how much raw iron is present. High-grade iron ore has a higher concentration of iron that low-grade iron ore. Typically, the concentration of iron is somewhere between 65 and 72 percent. Coke may be used for iron ore sintering. Different processing methods, such as sintering and ...
