  • QEMSCAN Analysis of Wadi-Shatti Iron Ore (Libya

    A Preliminary QEMSCAN analysis of Libyan iron ores samples was conducted at (advanced mineralogy research center- CSM) to determine phosphorous phases locking and liberation characteristics of the phosphorous phases and mineral associations. Determination shows that 61 Fe as Oxide/Hydroxide 31 quartz 5 apatite and other traces.

    The QEMSCAN package also incorporated QXRD work as an additional validation method. Three samples from the calibration experiments were selected for QEMSCAN analysis each representing a different size fraction. Two were selected from Brockman ores used in Experi-ment 2 and one was selected from the CID ore used in Experi-ment 3.

  • Comparison of the Mineralogy of Iron Ore Sinters Using a

    Many different approaches have been used in the past to characterise iron ore sinter mineralogy to predict sinter quality and elucidate the impacts of iron ore characteristics and process variables on the mechanisms of sintering. This paper compares the mineralogy of three sinter samples with binary basicities (mass ratio of CaO/SiO2) between 1.7 and 2.0.
