摘　　要：研究在有炭存在条件下用水蒸气氧化焙烧处理铁闪锌矿。在 70 0～ 90 0℃温度范围内 ,FeS中的硫能全部脱除 ,且大部分以元素硫的形式脱去 ,只产生少量H2 S和SO2 ,铁则基本上氧化成Fe3O4。The process of treatment of iron bearing sphalerite by oxidizing roasting with steam in the presence of powder carbon has been studied The experiments show that,between 700℃ and 900℃,the sulfur in FeS can be eliminated and most of them converted to elemental sulfur,together with a few of H 2S and SO 2,meanwhile,Fe is oxidized to Fe 3O 4
