Methods of separating a viscous hydrocarbon from an ore are conducted at an oil extraction facility. The methods include transporting a slurry to a separation vessel. The transport may take place substantially without the use of an air compressor and without the injection of air into the slurry along a hydro-transport line. The methods also include mixing a plurality of beads into the slurry. The beads have a specific gravity that is less than about 0.95. The beads are used in lieu of air. The beads have an outer oleophilic surface for retaining oil, thereby aiding in the separation process. The beads are substantially coated with bitumen prior to introduction to the slurry. The method then includes separating the slurry into a first solution comprising primarily bitumen and the oleophilic beads, and a second solution comprising primarily water and sand.
