Method and apparatus for separating slurries and emulsions
A mixture containing dispersed phase and continuous aqueous phase, with particulate solids being part of either or both phases, is separated by passing it one or more times through apertures in an endless oleophilic conveyor belt in a separation zone wherein bitumen phase adheres to the belt and bitumen adhering to the belt is conveyed to one or more bitumen treatment zones and to a recovery zone where bitumen is removed from the belt. The end rolls of the belt are not immersed in a water bath; however, portions of the belt, while in the separation, treatment and recovery zones, may be partly or completely in an aqueous environment. More than one set of separation, treatment and recovery zones may be used on the same endless belt conveyor. Also, a mixture containing dispersed aqueous phase and continuous bitumen or oil phase, and possibly gas, is deposited onto an apertured oleophilic endless belt conveyor and is treated in one or more treatment zones and is then removed from the belt.
