  • Direct reduced iron - Wikipedia

    Direct reduced iron (DRI), also called sponge iron, is produced from the direct reduction of iron ore (in the form of lumps, pellets, or fines) into iron by a reducing gas which either contains elemental carbon (produced from natural gas or coal) or hydrogen. When hydrogen is used as the reducing gas there are no greenhouse gases produced. Many ores are suitable for direct reduction. 2019年1月1日  The use of coal in reduction of iron ore is associated with pollution and greenhouse gas emissions, particularly CO2 (Yilmaz and Turek, 2017). The supply of A review of ironmaking by direct reduction processes: Quality ...2024年4月26日  Iron ore processing is a complex and vital process that transforms raw iron ore into usable steel. From exploration and extraction to grinding, beneficiation, and Iron Ore Processing: From Extraction to Manufacturing

  • Iron processing - Smelting, Refining, Alloying Britannica

    Smelting reduction employs two units: in the first, iron ore is heated and reduced by gases exiting from the second unit, which is a smelter-gasifier supplied with coal and oxygen. 2023年11月10日  Currently the majority of the world's steel is produced through either one of the two main routes: i) the integrated Blast Furnace-Basic Oxygen Furnace (BF-BOF) A REVIEW OF IRONMAKING BY DIRECT REDUCTION PROCESSES: 2019年7月19日  DRI is produced through the removal (reduction) of oxygen from iron ore in its solid state. This technology encompasses various processes based on different Direct Reduced Iron: Most Efficient Technologies for Greenhouse ...

  • From Ore to Alloy: Navigating Ironmaking in Modern Steel

    Processes like the Midrex and HYL/Energiron systems utilize natural gas or hydrogen to reduce iron ore pellets or lumps, yielding direct reduced iron (DRI) or sponge iron. These 2011年10月15日  Beneficiation steps include crushing, concentration, flotation, and/or roasting. The blast furnace is the dominant type of equipment for the production of iron Iron, 1. Fundamentals and Principles of Reduction ProcessesSince the focus of this paper is ironmaking, in this section we only briefly describe three ironmaking processes, i.e. the BF, direct reduction, and smelting reduction processes.
