ABSTRACT:
A method of removing aqueously soluble salt by-products produced by the treatment of raw titanium dioxide particles to add a finish thereto. The finished titanium dioxide particles with the salt are subjected to demineralization with mixed bed ion exchange resins to produce finished titanium dioxide particles substantially free of salt and salt forms of ion exchange resins. The finished titanium dioxide particles are recovered and the salt forms of ion exchange resins are regenerated to produce recoverable salt and reusable resins.
