Sintering plants are normally associated with the production of hot metal in blast furnaces in integrated steel pants.

The first step in the journey of producing steel from iron ore is the mining process, where ore is located and extracted from the earth. Once the ore is obtained, it is then subjected to a rigorous process of crushing and …

DRI steelmaking requires a higher grade of iron ore than blast furnaces, the dominant global technology. DR-grade iron oreideally has an iron (Fe) content of 67%or more and such deposits are scarce --only a small percentage of global seaborne iron ore comes close to DR-grade. " Iron Ore Quality a Potential Headwind to Green Steelmaking

The iron ore pellet screening is performed by depositing the raw material stream onto a roller screen to remove undersized pellets, separate on-sized pellets or remove oversized pellets or do both at the same time by using …

The various advantages of iron ore pellets are given below. Iron ore pellet is a kind of agglomerated fines which has better tumbling index when compared with the iron ore and it can be used as a substitute for the iron ore lumps both in the BF and for DRI production. Pellets have good reducibility since they have high porosity (25 % to 30 %).
