摘　　要：探讨了ＦｅＳ，ＳｉＯ２，Ｃ，ＣａＯ的加入量对镍转炉渣富集钴的影响，得到了ＦｅＳ，ＳｉＯ２量与Ｆｅ３Ｏ４还原率Ｒ的关系为：Ｒ＝９５００－２７５８５（ＦｅＳ％）ＦｅＳ＜３６５％Ｒ＝４０７０－２７２０（ＦｅＳ％）ＦｅＳ＜３６５％Ｒ＝５７８５＋１１４６０（ＳｉＯ２Ｓ％）The effect of adding FeS,SiO 2,C and CaO on concentration of cobalt from nickel converter slag has been studied.According to the experimental data,the relations between the Rate (R) of reduction of Fe 3O 4 and the amount of FeS,SiO 2 added are. R=95 00-275 85(FeS%) FeS<36 5% R=40 70-27 20(FeS%) FeS<36 5% R=57 85+114 6(SiO 2%) respectively.
