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
