Abstract

A hot water extraction process for extracting bitumen from tar sands is taught using a conditioning agent containing an alkali metal bicarbonate and an alkali metal carbonate. A source of calcium and/or magnesium ions can also be added. The conditioning agent replaces the caustic soda agent previously used intar sand extraction. The use of the alkali metal bicarbonate and carbonate substantially eliminates the production of sludge in tar sand extraction and maintains or improves bitumen recovery. The process allows for hot conditioning agent solution to be recycled to the process by use of a recycle storage tank.
