The FINEX is the latest addition and an optimized fine-ore smelting reduction (SR) iron making process based on the direct use of the coal and iron ore fines. FINEX Process is a fluidized bed based process using ore fines instead using iron ore lumps and pellets.
While most iron ore producers mine, market and sell a commoditized product that is effectively fungible across most blast furnaces, our production of custom-made pellets is the true differentiating factor when comparing Cliffs to its peers in the iron ore space.
Feb 26, 2018· How made binder for iron ore briquette? How can you describe the differences between iron ore lumps and iron ore fines? Name the finest iron ore? Wich si the actual price if iron ore? What are the similarities between iron ore lumps and iron ore fines? How do you make pigments from iron ore?
Iron Briquettes are produced by reducing iron ore fines in fluid bed reactors with a counter current reducing gas (Fluidized Iron Ore Reduction). Due to their high density and metallization, low gangue and residual content, and inert character, Iron HBI is the ideal metallic charge for steelmaking.
Abstract. Composite briquettes or pellets consisting of iron ore, carbon, and a binder are a source of direct reduced iron (DRI). In the handling of green and reduced briquettes, high strength is important to minimize briquette breakdown.
Iron ore must be shipped in bulk for maximum economy. 1.2 Pretreatment process In this process, the iron ore is ground into fines having qualities required for the subsequent balling process. The pretreatment includes concentrating, dewatering, grinding, drying and prewetting. In general, low-grade iron ore is ground into fines. Get price
3.2 Hot Briquette Iron (HBI)— HBI means briquettes made out of sponge iron/DRI produced in gas based direct reduction processes at elevated temperature by the application of external pressure in a more or less close mould. 3.3 Cold Briquettes — Cold briquettes mean cold bonded sponge iron/DRI briquettes, made from sponge iron/DRI fines only.
Iron ore is the raw material used to make pig iron, which is one of the main raw materials to make steel—98% of the mined iron ore is used to make steel. Indeed, it has been argued that iron ore is "more integral to the global economy than any other commodity, except perhaps oil ".
