direct reduction of iron plant schematics

    Sponge Iron Manufacturer India

    Sponge Iron also called Direct reduced iron (DRI), 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 for direct reduction. Direct reduction processes can be divided roughly into two categories: gas-based, and coal-based. In both .

    The major capital expenditure in a plant to make prereduced pellets is for kilns and coolers. Other items, beyond those required for conventional pellets, such as reductant bins and conveyors, add little to the depreciation charge per ton of product. Prereduced pellet plants cost more per product ton than those for oxide spheres largely because there is more iron in the metallized pellets.

    Iron ore pelletizing systems - Metso

    Iron Ore Pellets are formed from beneficiated or run of mine iron fines. The iron is usually ground to a very fine level and mixed with limestone or dolomite as a fluxing agent and bentonite or organic binders as a binding agent. If the ore is a Hematite ore, coke or anthracite coal can be added to the mix to work as an internal fuel to help fire the pellets. This mixture is blended .
