Abstract
Bitumen recovery from a tar sands emulsion or other bituminous oil-in-water emulsion is increased by milling the emulsion for a time sufficient to cause a bitumen-rich liquid fraction to rise to the surface, and separating such fraction. Addition of water to the starting emulsion or during milling further enhances the recovery of bitumen.
