Abstract:
A process of extracting bitumen from oil sand ores having a fines content up to about 60% and a bitumen content greater than 6% is provided, comprising: determining the fines content and the bitumen content of the oil sand ore; calculating a sufficient amount of caustic to be added in the process using an equation based on the ratio of the fines content to the bitumen content; mixing the oil sand ore with heated water to produce an oil sand slurry; and adding the sufficient amount of caustic before, during or after mixing the oil sand ore with heated water to condition the oil sand slurry and to improve bitumen recovery from the oil sand ore.
