| Abstract: |
| Due to massive production, high alkalinity and intractable utilization, the sustainable development of alumina industry is significantly limited by disposal of red mud. In order to reduce environmental pollution and improve resource utilization, numerous researches have been carried out on comprehensive utilization of red mud. However, cleaner utilization of red mud is still an urgent issue to be solved. Soilification is a feasible method for massive consumption of red mud. This review surveys current status, and discusses future research directions from the aspects of evolution of red mud dam, alkaline regulation, soil regulation and phytoremediation. Theoretical and technical guidance for cleaner disposal and phytoremediation of red mud are provided. |
