Abstract
A process for operating multiple oil sand mine sites for extracting bitumen from oil sand is disclosed, comprising preparing a first conditioned oil sand slurry at a first location using a first oil sand slurry preparation and slurry conditioning process; preparing a second conditioned oil sand slurry at a second location using a second oil sand slurry preparation and slurry conditioning process; combining the first conditioned oil sand slurry and the second conditioned oil sand slurry in at least one slurry distributor to produce a combined oil sand slurry; and distributing the combined oil sand slurry to at least one separation vessel to produce bitumen froth.
