Abstract
A method is disclosed for the recovery of bitumen from a sludge. The sludge is diluted with water and subjected to high-shear agitation and aeration and the sludge settled to obtain an upper bitumen-containing froth layer and a lower sludge layer of reduced bitumen content. The recovery of bitumen is increased over that obtained with aeration and mixing with mild agitation or with aeration alone or with agitation alone.
