The recovery and utilization of iron resources from red mud is of great significance to supplement the iron ore resources in China. The production process described in this paper utilizes the red mud produced after the extraction of alumina from high iron content bauxite to extract iron, and obtains iron concentrate through the process of red mud-slag screening-medium magnetic machine-roughing-cleaning-filter press. The process has the advantages of mature and reliable technology, low CAPEX and OPEX, and slight impact on the alumina process system.
