【Abstract】 On the bases of analysis of crystal chemistry reaction of low-grade refractory iron ore in reduction process,the effect of reduction temperature on coalescence growth of iron crystalline grain and separation of slag and iron was investigated.In addition,the catalytic effect of reduced iron powder on reduction process,and its effect on seperation of slag-iron were also studied.更多还原
