Abstract

Abstract

The process of blast furnace iron-oxygen top blowing converter blowing vanadium extraction-vanadium slag followed by sodium roasting-water leaching and vanadium extraction will form vanadium tailings containing 30%～40% Cr₂O₃, forming an annual accumulation of millions of tons of solid waste. In this study, the vanadium tailings were extracted by synergistic reduction of high-iron red mud, and the Fe₂O₃ in the red mud was reduced by carbon at a temperature lower than the initial reduction temperature of chromium oxide, which promoted the rapid progress of chromium reduction and improved the recovery efficiency of Cr. The whole reaction system was simulated by FactSage thermodynamic software, and the effects of the chromium iron ratio, slag alkalinity and C/Si content on the partition behavior of chromium and sulfur were calculated. The suitable Cr/Fe ratio of the raw materials was 0.18, the alkalinity of the slag was 1.8, the amount of carbon was n_C/O = 1.1, and the amount of Si was n_Si/O = 0.2. This study provides a new feasible scheme for the resource treatment and value-added application of Cr-containing vanadium tailings and high-iron red mud.
