Sintering A Step Between Mining Iron Ore and Steelmaking

The iron ore sintering process prepares fine iron the ores for the blast furnace process Sinter plants agglomerate iron ore fines with other fine materials at high temperature in a mix bed to create a product that can be used in a blast furnace Main feed into a sinter plant is base mix which consists of iron ore which includes sintering and blast furnace processes and only the sintering process represents around 20 of this amount15 Therefore sintering and blast furnace processes offer good opportunities to decrease the CO 2 emissions since mall decreasing of the coke breeze consumption and bonding agent used in iron ore sintering process
