  • Direct Reduction Process an overview | ScienceDirect

    The basis of the direct reduction process is that solid sponge iron is produced by removing oxygen from the ore in a shaft furnace, rotary kiln furnace or fluidised bed Sponge iron can be produced in the form of Direct Reduced Iron (DRI), Hot Briquetted Iron (HBI) and Cold Briquetted Iron (CBI); also Low Reduced Iron (LRI), which is prereduced iron ore with a reduction and metallisationTunnel Kiln history dates back to 1807 when Hoganas first used this process to produce iron powder of 999% purity When iron ore is mined or processed (in a crusher), lots of fines are generated Quantity of fines generation is a function of the quality of ore ie whether it is hard or soft Iron ore fines are usually subject to beneficiation and/or pelletisation thereby converting them backTunnel Kiln – Electrotherm – Engineering & TechnologiesBoth hematite and magnetite ores can be used in the tunnel kiln The process is more suitable for soft ores, such as blue dust The tunnel kiln process can reach higher metallisation levels of 9092%, as compared to 8688% in the rotary kiln The first generation tunnel kilns used clay crucibles and the capacities were 10,00025,000 tons perReduction of iron ore briquettes into DRI in the tunnel
