• Hazard Identification, Risk Assessment, and Control

    The waste water from iron ore slurry is separated through filtration system and treated in the thickener. In the thickener, all dedusting/scrubber return water is passed and the underflow is reused in the process. The pellet plant has a goal to achieve zero discharge norms with a comprehensive water and waste water management.

    One such procedure is the Japanese Direct Iron Ore Smelting (DIOS) process (Figure 2). The DIOS process produces molten iron from coal and previously melted ores. In this process, coal and other ores can produce enough heat to melt ore, replacing coke completely (USEPA, 1995).

  • Direct reduced iron plant

    Jul 12, 2021Direct reduced iron (DRI), also called sponge iron, is produced from the direct reduction of iron ore (in the form of lumps, pellets, and/or fines) into iron with a spongelike exterior, without melting. The heart of the direct reduction is the shaft furnace, which is filled from the top with lump ore and pellets. DRI production turns iron ore into iron using gaseous reducing agents such as

  • EFFECT OF MAGNETITE, HEMATITE AND PELLET

    addition of 20% of LKAB iron ore concentrate to the sinter blend, has no significant impact on productivity. On the other hand, addition of 20% pellet screenings prove to have a positive effect compared to the reference case. From the results, the addition of 20% pellet screenings increase the productivity by slightly more than 7%.

  • Iron Extraction Process

    At the bottom of the furnace the iron ore is chemically reduced. The blast reacts with the coke; carbon dioxide and carbon monoxide are formed at temperatures of up to 2000 C. The carbon monoxide removes the oxygen from the iron ore resulting in pig iron production. Slag is formed from the other ore components and the additions.
