Flotation Separation of Nanyang Kyanite Ore

Article Preview

Abstract:

It is a developing trend for the refractory materials industry that producing refractories using the kyanite ore with minute amounts of titanium. The tests were conducted with an ore sample by a mechanical flotation cell. The isoelectric point of the kyanite ore was found to be pH 6.6. Petroleum sulfonate was found to be an effective collector for kyanite flotation. 55.85% Al2O3 is produced with 84.41% kyanite recovery by grinding, desliming, reverse flotation and kyanite flotation.
