Based on an overview of progress in the research on iron recovery from high-iron red mud by alkaline electrolysis, the research findings at home and abroad are introduced in terms of principle and advantages of electrolysis, influencing factors for the process, and the obtained iron products. The advantages of red mud in the process for preparing metallic iron by electrolytic reduction of red mud in alkaline media at low temperatures are elaborated, and some problems to be solved in the future are proposed, which can provide references for innovation and development of this process.
