Abstract

A process is provided for treating an aqueous oil sand slurry containing bitumen droplets and air bubbles prior to separation in a separator, comprising separating the aqueous oil sand slurry into at least two individual slurry streams and allowing the at least two slurry streams to collide with one another such that the bitumen droplets and air bubbles in each slurry stream make contact with one another to increase both collision frequency and efficiency, and providing sufficient residence time to allow the bitumen droplet to coalesce, grow, and aerate to produce a treated oil sand slurry with larger and lighter bitumen droplets to improve bitumen flotation and recovery.
