Abstract
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 components, wherein the steps of physically extracting iron components and physically extracting aluminum components are performed without requiring addition of chemical additives to the red mud.
Claims24
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 components,
