based on feed • Not Yet

Problem being addressed Techno-economics

• This technology can help in recovering- iron values • NA
from redmud which is generated as a waste during
refining of bauxite for production of alumina.
Technology Package
• Concept to development of process
Environmental Considerations (if any) flowsheet
• Can mitigate the environmental impact

Major Raw Materials to be Utilized
• Red mud

IPR Status / Details (India/Abroad)
• Process know how

Application/Uses
• The redmud generated during Bayers process of
alumina production, contains around 30-60% iron
which can be recovered with a product having
commercially usable iron grade and yield.
