  • Direct reduced iron Wikipedia

    Direct reduced iron. Directreduced iron ( DRI ) also called sponge iron is produced from the direct reduction of iron ore (in the form of lumps pellets or fines) to iron by a reducing gas or elemental carbon produced from natural gas or coal. Many ores are suitable

  • Direct Reduced Iron and its Production Processes IspatGuru

    Major DRI production processes are either gas based or coal based. Feed material in a DRI process is either iron ore sized to 10 to 30mm or iron ore pellets produced in an iron ore pellet plant. In the gas based plant the reactor the reduction reaction takes place is a shaft furnace. The shaft furnace works on counter current principle where the iron ore feed material moves downward in the furnace by

  • Iron Production Chemistry LibreTexts

    The production of iron from its ore involves an oxidationreduction reaction carried out in a blast furnace. Iron ore is usually a mixture of iron and vast quantities of impurities such as sand and clay referred to as gangue. The iron found in iron ores are found in the form of iron oxides. As a result of these impurities iron must be first separated from the gangue and then converted to pure
