  • PELLETISATION Metal Bulletin

    •Pelletisation process is to make use of Blue dust and ultra fine concentrate generated in the Iron ore beneficiation plants. • Pellets have the benefit of lower gangue on account of beneficiated ore. •The excessive fines generated from the iron ore mining and crushing units for sizing the feed for blast furnace and sponge iron ore plants areDirect Reduction of Iron Ore with Green Hydrogen,2020-2-9 · Direct reduction of iron ore refers to the conversion of solid iron ore to metallic iron without conversion to the liquid phase [37]. Majority of the direct reduced iron (DRI) [38] is produced by reacting iron oxide with hydrocarbon-based reducing gases produced from reforming natural gas or coal gasification [39–42].

    2020-2-2 · High grade iron ore less than 10% of the total reserves. ROM iron ore with Fe less than 58 60% discarded as waste. After beneficiation iron ore availability can improve by about 50%. Steel community and the country demand technological solutions for utilising low grade ores. The technology task that would be imperative: 1.Pollution in the sponge iron industry SlideShare,2013-7-31 · DRI, or directly reduced iron is a method of producing solid iron from iron oxide 2 3. Iron from iron ore can be • In solid form In solid form, iron ore can be 1. DRI produced in coal based kilns 2. HBI produced in gas based kiln. 3. DRI does not need coking coal at all. • Or in molten form In molten form iron can be produced in the 1.
