The Sintering Process of Iron Ore Fines IspatGuru
Use of sinter reduces the coke rate and enhances the productivity in blast furnace. Sintering process helps utilization of iron ore fines (0-10 mm) generated during iron ore mining operations. Sintering process helps in recycling all the iron, fuel and flux bearing waste materials in the steel plant.
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.
Sinter plant Wikipedia
Sinter plants agglomerate iron ore fines (dust) with other fine materials at high temperature, to create a product that can be used in a blast furnace. The final product, a sinter, is a small, irregular nodule of iron mixed with small amounts of other minerals.
