Abstract：Separated granulating sintering was a kind of new sintering process, which included making the concentrate ore into high R material and acidic ball separately, mixing with fuels and returned mine, and taking the compound sintering. The study results show: with the increase of carbon content, the content of calcium ferrite of sinter is decreased, the content of CaO·TiO2 of sinter is increased, the content of hematite of sinter is decreased, the TI and RDI of sinter is improved, the RI of sinter is deteriorated. In summary, high carbon content was not conducive to quality of sinter. It should be around 4.2%.
