Patent

CA 2524110

A bitumen recovery process is provided which includes the step of providing a bitumen froth or a component derived from the bitumen froth as a feed material, wherein the bitumen froth is produced in a primary separation process from a slurry comprising oil sand and water. Further, the process includes the step of subjecting the feed material to froth flotation in a column flotation cell in order to recover a bitumen product from the feed material. Preferably, the froth flotation cell includes an underwash zone, wherein a bitumen-rich fraction of the feed material is passed through the underwash zone as the bitumen-rich fraction rises within the column flotation cell.
