Abstract
A process for extracting bitumen from oil sand ore to produce a bitumen froth having reduced solids is provided, comprising mixing the oil sand ore with water and a first process aid comprising at least one surfactant to form an oil sand slurry; conditioning the oil sand slurry to produce a conditioned oil sand slurry; and introducing the conditioned oil sand slurry into a separation zone for forming the bitumen froth having reduced solids.
