Summary:The present invention provides a method for smelting ilmenite using red mud, the method comprising the steps of: mixing an ilmenite concentrate and red mud to form a mixture; adding a carbon source to the mixture, followed by heating to reduce iron in the mixture to form a molten droplet; subjecting the molten droplet to magnetic separation to remove the iron and recover a titanium dioxide slag; introducing the titanium dioxide slag into a Bayer process to recover alumina (Al
