  • Influence of Alumina on Iron Ore Sinter Properties and

    Ore with higher alumina content is usually expected to be detrimental in forming the sinter matrix, if sintered alone, due to the low reactivity of alumina bearing minerals and the high viscosity of primary melts. The selective granulation process is a new sintering process for high alumina iron ore fines, and can eliminate the adverse effects

  • Characterization of Chemical Composition and

    The iron ore from Kashenyi hill (Ug6) has high alumina content (6% Al 2 O 3). However, the silica content (5.1% SiO 2 ) in this ore is just below the acceptable level. Overall, based on the analysis of SiO 2 and Al 2 O 3 contents, it may be concluded that the iron ores of Muko deposit can serve well as a good raw material for iron production.
