[email protected]effect of magnetite, hematite and pellet screenings as feed in sinter production mikael pettersson1, peter sikstrm1 and dr.Volker ritz2 1lkab, 952, 971 28 lule, sweden 2sga, grubenstrasse 5, 38704 liebenburg, germany abstract during the last years, the availability of coarse, high quality sinter feed has decreased.
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.
Read MoreHowever, the quality of domestic concentrate remains a major limiting factor.Pellet feed imports are likely to rise, as chinese mills will require higher grade, lower impurities and consistent magnetite products for blending with domestic material.So what? the implications of china's 'shift-to-pellet' go beyond the pellet/pellet feed market.
