 — This paper presents mass accounting models that trace the flow of major individual elements from iron ore through to iron lumps, pellets or sinter, the transformation of these intermediate products into pig iron (PI) or direct reduced iron (DRI), and the transformation of PI and DRI into crude steel in a basic oxygen furnace (BOF) or electric …

 — With the intensified depletion of high-grade iron ores, the increased aluminum content in iron ore concentrates has become unavoidable, which is detrimental to the pelletization process. Therefore, the effect mechanism of aluminum on pellet quality must be identified. In this study, the influence of aluminum occurrence and content on the …

 — How Are Iron Ore Pellets Made? Here's a quick introduction for you on how Pellets are made. Usually, Iron Ore is manufactured and converted into Pellets. These are oval lumps of iron ore that are hardened using fuel. This process of converting iron ore into pellets is known as Pelletization. Iron Ore Pellets are then used in the production of ...
