  • Hydrogen Reduction of Hematite Ore Fines to Magnetite Ore

    The conversion of Fe 2 O 3 in the hematite ore played an important role in the total iron recovery and grade of the concentrate. The grade of the concentrate decreased, whereas the total iron recovery increased with the increasing Fe 2 O 3 conversion. Surplus coke oven gases (COGs) and low grade hematite ores are abundant in Shanxi, China. Our group proposes a new process that could

  • Trade review: Soaring iron ore prices bring buying

    Platts 62% Fe benchmark iron ore fines index, or Platts IODEX, averaged $118/dry mt CFR China in Q3. After a slower July, prices surged to a six-year high of 127.60/dmt on Aug. 18, before strengthening further to $130.80/dmt on Sept. 3, the highest since January 2014. The surging cost of mainstream medium grade fines prompted mills with flexibility in their blending ratios to scout for cheaper

  • Iron ore pricing explained | Metal Bulletin

    Inter-grade price spreads tend to expand during these times, and high-grade indices such as the MBIOI-65-BZ and Metal Bulletin 66% Fe Concentrate Index (MBIOI-CO) usually extend their premiums to the MBIOI-62 and Metal Bulletin 58% Fe Iron Ore Index (MBIOI-58). Conversely, when margins fall away, mills look to the cheaper low-grade ores to reduce costs and minimize their production rates.

  • Reade Advanced Materials - Magnetite / Black Iron Oxide

    It is one of the important ores of iron (magnetic iron ore) and is a common constituent of igneous and metamorphic rocks. It is found in various parts of the United States, Norway, Sweden, and the Urals. A variety of magnetite, lodestone (or loadstone) exhibits polarity and is especially interesting for its natural magnetism; Magnet Cove, Ark., became famous as a source.

  • Iron ore - Wikipedia

    The typical grade of iron at which a magnetite-bearing banded iron formation becomes economic is roughly 25% iron, which can generally yield a 33% to 40% recovery of magnetite by weight, to produce a concentrate grading in excess of 64% iron by weight. The typical magnetite iron ore concentrate has less than 0.1% phosphorus, 3–7% silica and less than 3% aluminium. Currently magnetite iron
