Abstract
A process for recovering heavy minerals (e.g., titanium minerals such as TiO) from a feedstock comprising tar sands or a tar sands-derived solids fraction. The feedstock comprises bitumen and heavy minerals. The process comprises the steps of: (i) contacting the solids fraction with water at a temperature of at least about 100° F. to cause production a bituminous phase and a heavy minerals phase; and (ii) separating the heavy minerals phase from the bituminous phase. Optionally, these steps may be preceded by one or more steps used to produce a tar-sands derived solids fraction from a tar sands feedstock.
