  • Effect of Fluxing Agents on the Quality and

    2017-6-1  Indian iron ore fines with high alumina content (~2.5% Al 2 O 3 ) resulted in poor quality pellets and a study was under taken to establish suitable pellet chemistry through proper fluxing agents. Limestone fluxed pellets were prepared at varying basicity (0 to 0.8) and pyroxenite fluxed pellets at varying MgO contents (0 to 3%) to study their effect on the metallurgical properties.

  • Magnetite - an overview ScienceDirect Topics

    Unlike magnetite concentrates, hematite concentrates, especially specularite and pyrite cinder, are harder, denser with smooth surfaces, and less hydrophilic. Therefore, they are usually much more difficult to pelletize and require higher bentonite dosages and firing temperatures to achieve the minimum green and fired pellet quality.
