    1. 283. PHASE DEVELOPMENT OF TITANOMAGNETITE IRONSAND DURING OXIDIZING CONDITIONS.
      Mr Oscar Bjareborn (Victoria University of Wellington, New Zealand)

      Oral Presentation
      New Zealand ironsand is an unconventional titaniferous ore (typically ~8% TiO2 by mass) which is commercially utilised to produce DRI, and as a blending component within BF sinters. Oxidative sintering of this titanomagnetite sand enables high-strength porous pellets to be formed, and such pre-oxidation is known to significantly enhance the gas-solid reduction rate compared to unoxidised...

      Pelletising
      Oral Presentation
      The straight grate and grate kiln indurating processes are the two proven and widely accepted iron ore pelletizing technologies. Hatch performed a technical and economic comparison between the two processes, emphasizing their specific advantages and applicability for selected regional conditions. The technology comparison is based on publicly available literature and our extensive database of...

    3. 103. RESEARCH ON PELLETS PROPERTIES PREPARED WITH DIFFERENT FINENESS FORSTERITE
      Prof. Jianliang Zhang (University of Science and Technology Beijing & the University of Queensland)

      Pelletising
      Oral Presentation
      Basic characteristics of forsterite were systematically studied by chemical analysis, XRD, SEM-EDS. A series of experiments were performed to investigate the effect of forsterite fineness on pellets strength and porosity by changing pre-grinding time of olivine. It could be found that prolong the pre-treatment time of forsterite is beneficial to the promotion of pellets strength; there are two...

    4. 29. A NEW 3D CHARACTERIZATION TECHNIQUE FOR MINERALOGICAL STRUCTURE OF IRON ORE PELLET
      Prof. Wei Wang (Wuhan University of Science and Technology)
      26/09/2018, 14:50
      Pelletising
      Oral Presentation
      With the rapid development of iron and steel industry in China, the iron ore pellet as an essential raw material plays an important role in the blast furnace. Due to large-scale production of iron ore pellet, microscopic characterization is an important step in quality control. The structure and distribution of minerals in a pellet and the bonding types at point contacts between the grains...

    5. 32. REDUCTION BEHAVIOURS OF PELLET BY HYDROGEN AND CARBON MONOXIDE ATMOSPHERES USING IN-SITU XRD AND THERMOGRAVIMETRIC ANALYSISES
      Prof. yaowei yu (shanghai university)
      26/09/2018, 16:00
      Pelletising
      Oral Presentation
      Canadian hematite acid pellet with low magnetite content fluxed and olivine were isothermally reduced with hydrogen and carbon monoxide at 600 to 1000℃. The course of reduction was investigated by measuring the oxygen weight loss as a function of time using a thermogravimetric analysis. Macroscopic and microscopic examination, X-ray and carbon analyses were also used to elucidate the...
