Abstract
A system for processing red mud comprising: a first heating section controlled to heat red mud to a first temperature; a second heating section controlled to heat the red mud to a second temperature lower than the first temperature; a crusher configured to grind the red mud to a predetermined particle size; and one or more separators for physically extracting at least iron and aluminum from the red mud.
Claims19
A method of processing red mud comprising:
- sanitizing red mud at a temperature of at least 1400° C. to remove caustic soda from the red mud;
- grinding the red mud to a predetermined particle size;
- and
- physically extracting at least iron components and aluminum components from the red mud so as to separate the iron components from the red mud and to separate the aluminum components from the red mud,
- wherein the sanitizing step further includes converting silicon components to glass.

A method of processing red mud comprising:
- heating red mud to remove caustic soda from the red mud;
- 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 adding chemical additives to the red mud.
