Effects of Iron Ore Type and Gangue Mineral Components on Strength of Sintered Fine Powder Granule

Depletion of high-grade iron ore resources leads to increasing use concentrates as raw materials for sinter. One the methods effectively utilize such is Mosaic EmBedding Iron Ore Sintering (MEBIOS), which pre-granulated green pellets are charged into sintering bed with mixture other materials. In this study, effects type and gangue mineral components on strength sintered pellet prepared fine were examined. Green using hematite magnetite ores, burnt lime alumina mullite reagents, then at 1300°C. The increases basicity (CaO/SiO2, C/S) lower region. C/S above 1.5 showed higher than 980 N. It can be attributed melt formation during sintering. On hand, when ore, N was obtained = 1.0. reason an acceleration solid-state by volume expansion due oxidation hematite. Increasing Al2O3 content decreasing because prevented amount formed melt.
