Abstract: Red mud is a solid residue discharged from the production process of alumina.With the rapid development of alumina industry，it is rather urgent to comprehensive utilize it effectively.The physical properties，chemical composition，and mineral constituent of red mud from bayer process in Guizhou Aluminum Works were studied.And the research progress of red mud utilization in China and abroad was analyzed in detail from three aspects，i，e，overall employment of red mud in building materials，extraction of valuable elements，and environment-friendly materials.On the basis of that，the technical difficulties and limiting factors of comprehensive utilization of red mud from bayer process in Guizhou Aluminum Works were analyzed in detail.At the end，according to the physicochemical characteristics of red mud from bayer process in Guizhou Aluminum Works，the ideal mode of comprehensive utilization of red mud was discussed，and a new technology of comprehensively and high-efficiently reusing red mud was proposed.
