Zusammenfassung:The invention is directed to a process for extracting bitumen from poor oil sand ore involving mixing the poor oil sand ore with heated water to produce a slurry, and conditioning the slurry to yield a poor ore stream. In a separate train, good oil sand ore is mixed with heated water to produce a slurry, and conditioned to yield a good ore stream. Both the conditioned poor ore and good ore streams are combined in specified proportions to yield a blended slurry which is then fed to a primary separation vessel to produce primary bitumen froth.
