Red mud (RM), also called bauxite residue, is a strong alkaline industrial waste generated during the alumina production process. The annual production of RM in China is large, but its average utilization rate is low (only 4%). High generation and low consumption make the disposal of RM mainly by stockpiling, which has caused serious heavy metal pollution and radioactive contamination.
What is claimed is: 1. A method of processing red mud comprising: heating red mud to a predetermined temperature; grinding the red mud to a predetermined particle size; and physically extracting iron components from the red mud; physically extracting aluminum components from the red mud, said physically extracting of aluminum components being separate from the physically extracting of iron ...
utilization of red mud for iron production have a long history [30]. For instance, before and during the Second World War, the red mud was dried by the German iron and steel industry on deck ovens and sold as a catalyst for the liquid phase of the coal hydrogenation. The active component thereby formed finely divided iron hydroxide.
The mining of layered soft bauxite under coal seams (BCS) will cause serious underground goaf disasters and surface Bayer process red mud (BRM) pollution.
