| titleOfInvention | Upgrading ilmenite for titania production |
| abstract | The present invention provides a process for upgrading a primary ilmenite containing gangue mineral grains for forming titania pigment by the sulfate method, the process including the step of: roasting a primary ilmenite containing gangue mineral grains at a temperature of less than 650 °C under conditions that promote the formation of a magnetically separable product rich in titania and in which the rutile present is in a form that is at least partially soluble in concentrated sulfuric acid.The process will typically involve the step of: subjecting the roasted ilmenite concentrate containing gangue to magnetic separation to reduce the content of gangue mineral grains and provide a product rich in ilmenite and containing rutile. |
