Abstract：The reduction experiment was carried out, using carbon-bearing pellets which were mainly made of iron concentrate, pulverized coal and limestone, at 1573K, 1623K, 1673K with different heating time. The distribution of sulfur was also calculated. The results show that: at 1673K, 12min, iron nuggets and slag can separate well. The carbon and sulfur content of nuggets is 3.53% and 0.17%, the internal organizational structure of nuggets consists mainly of pearlite and cementite. The slag mainly contains calcium silicate (CaSiO3) and dicalcium silicate (Ca2SiO4), and the others are monticellite (CaMgSiO4) and vitreous. About 24.61% of sulfur is entering the slag, and 61.91% into the iron, 13.48% get into the air.
