  • Hydrogen Reduction of Hematite Ore Fines to Magnetite

    AbstractIntroductionMaterials and MethodsResults and DiscussionsConclusionsAcknowledgmentsSurplus coke oven gases (COGs) and low grade hematite ores are abundant in Shanxi, China Our group proposes a new process that could simultaneously enrich CH4 from COG and produce separated magnetite from low grade hematite In this work, lowtemperature hydrogen reduction of hematite ore fines was performed in a fixedbed reactor with a stirring apparatus, and a laboratory Davis magnetic tube was used for the magnetic separation of the resulting magnetit
  • Hydrogen Reduction Kinetics of Hematite Concentrate

      As an integral part of developing a novel ironmaking process, the hydrogen reduction kinetics of hematite concentrate particles (average particle size 21 µm) were measured in the temperature range from 1423 K to 1623 K (1150 °C to 1350 °C) The novel ironmaking process aims at producing iron from iron oxide concentrates in a flash reactor using gaseous fuels and
