This invention relates to a process for separating rutile and ilmenite from ilmenite leach tails and is effected by treating the leach tails from an acidic leach to a flotation step whereby gangue is separated from the unreacted ilmenite and rutile. The latter is then roasted at an elevated temperature in a hydrous atmosphere to convert the ilmenite to a magnetic material.
The effects of corrosion temperature, oxygen flow rate and corrosion time on the transformation of metallic iron were systematically studied, and the effects of mineral phases of Fe-bearing products on Ti–Fe separation were investigated. The reaction mechanism of metallic iron in corrosion process was proposed. The results showed that corrosion temperature played …
However, ilmenite is also mixed with impurities, it must be separated to obtain the high grade ilmenite. At present, the main separation methods include flotation [3,4], gravity, magnetic separation [6,7], and so on. For example, decanoic acid was found to be an effective collector, to float ilmenite in the strongly acidic pulp.
