A method is described for the recovery of zircon and rutile from bituminous tar sands. The process includes the steps of recovering a mineral-containing bitumen froth from a separation process for the treatment of bituminous tar sand, diluting the froth with a liquid hydrocarbon diluent, centrifuging at least a portion of the mineral-containing diluted bitumen froth to produce a bitumen product and a waste stream comprised of heavy minerals including zircon and rutile, as well as bitumen, diluent, and water. Subsequently, the heavy mineral stream is mixed with a solvent to remove the bitumen and other contaminants adhering to the surface of or mixed with the metal particles. The clean particles are washed with hot water and dried. The hydrocarbon solvent contains at least 10% by wt aromatics. (7 claims)
