Abstract

In order to realize the large-scale resourcefulness and harmless utilization of high-iron red mud, a pilot-scale experiment on vortex smelting reduction of high-iron red mud was conducted using conditions determined on the basis of laboratory research. The pilot study achieved good results. The iron recovery was 97.12%, and a pig iron product containing 93.27 wt % iron was obtained. The experimental conditions included a temperature of 1500 °C, a carbon ratio of 1.3, a holding time of 30 min, a stirring speed of 125 rpm, an alkalinity of 1.0, and fluorite was used as a co-solvent at 10% of the calcium oxide addition. The concentrations of P and S in the pig iron were low, which allowed them to meet the requirements of the national standard L03 for steelmaking. The main phases in the reduction slag were gehlenite, calcium titanate, and nepheline, which were effective components for cement clinker production.
