ABSTRACT: The sintering of limonite ore is a recent cost-effective method of iron production. In this study, the influences of sinter binary basicity and calc-flux type on the quantity, strength, and type of sintering bonding phases, as well as on sinter quality under high limonite ratios, were investigated by an experiment based on the characteristics of ore blends. Production of sinters demonstrates that, under high limonite ratios, sinter quality can be improved by increasing the binary basicity of sinters, the ratio of quicklime, and the height of the sintering bed.
