Process for separating bitumen from a bitumen sand deposit

Patent ·
OSTI ID:5689875
;
Bitumen is separated from a bitumen tar deposit by a mechanical separation process which does not require high energy consumption. The process includes the steps of feeding the bitumen sand and a dispersing medium into an enclosed container having a number of arms which rotate about a central axis, each arm having a blade at the end. The arms are rotated striking and impelling the sand particles to impact on internal surfaces of the blades and container and with other particles, the blades having sufficient tip speed to cause separation of the bitumen coatings from the particles. The sand particles, bitumen and dispersing medium are discharged from the container, and the bitumen is collected separately from the sand particles and dispersing medium. 5 claims.
