Research progress on utilization technology of red mud
Red mud is the polluting industrial waste residue produced in the process of alumina production.A large amount of stacking not only occupies the land,but also causes serious environmental pollutions,so it is imperative to develop comprehensive utilization technology of red mud.The application of red mud in the fields of building materials(including production of cement,building bricks,light insulation materials,glass ceramics),wastewater treatment,waste gas adsorption,extraction of valuable elements(iron,titanium,scandium)and agricultural production was introduced.The development of green,low-carbon and large-scale comprehensive utilization technology was the focus of red mud treatment in the future.
