  • Separation of rutile from ilmenite - Google Patents

    Rutile may be separated from ilmenite or ilmenite ores by agitating a mixture of ilmenite and rutile in particle form in an aqueous solution containing a collection agent to which hydrogen peroxide has been added. The slurry in agitated form is treated with air to produce a froth. The ilmenite particles will attach themselves to the air bubbles in the froth and may be skimmed off the surface ...

  • Separation of ilmenite and rutile - Google Patents

    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.
