Iron Ore Pellet Making Process

  • Reduction of Iron Ore Pellets, Sinter, and Lump

    There have been studies about the low‐temperature reduction degradation characteristics of pellets, sinter, and lump ore, [] as well as the softening, shrinking, and melting reduction behavior of all charge materials or just part of them. [3-9]Even though some research has considered all iron‐bearing materials (sinter, iron ore pellets, and lump ore), the authors were not able to find

  • Iron ore pricing explained | Metal Bulletin.com

    Sinter fines and lumps make up the bulk of the seaborne iron ore market, and are the products most frequently traded on a spot basis, so daily pricing is used for the key 62% Fe, 58% Fe and 65% Fe fines, and lump premium references. By contrast, the beneficiated ore segment - comprising pellet and concentrate - is smaller in terms of both volume and liquidity, and weekly indices are therefore

    In a DR process, iron ore pellets and/or lump iron ores are reduced by a reducing gas to produce DRI or hot briquetted iron (HBI). Depending on the generation of the reducing gas, two different DR processes are commercially available: gas-based and coal/oil-based. In the gas-based DR process, the reducing gas is produced by chemically reforming a mixture of natural gas and off-gas from the
