An oily mass of solids tailings is derived from flotation of bitumen during hot water extraction of bituminous sands, and subsequent separation of most of the bitumen from associated solids. This oily mass contains a high concentration of heavy minerals, in the order of 10% by weight titanium and 4% zirconium. The tailings are introduced into a hot reaction zone and contacted with oxygen while agitating the solids. The bitumen associated with the solids is burned, as is residual coke left from the combustion of the bitumen. The product particles are discrete, dry and clean. They can be slurried with water and passed through gravity concentrating means, such as a spiral, to produce a concentrate containing in the order of 18% titanium and 8% zirconium. 2 figs.
