Abstract
A process for extracting bitumen from weathered oil sand ore is provided, comprising mixing the weathered oil sand ore with heated water and sodium triphosphate to form a weathered oil sand slurry; adding sodium triphosphate to either the weathered oil sand ore, the heated water, or to the weathered oil sand slurry; conditioning the weathered oil sand slurry at a temperature of at least 50°C to form a conditioned weathered oil sand slurry; and subjecting the conditioned weathered oil sand slurry to gravity separation at a temperature of at least 50°C to form a bitumen froth product.

adding sodium triphosphate to either the weathered oil sand ore, the heated water, or to the weathered oil sand slurry;
conditioning the weathered oil sand slurry at a temperature of at least 50°C to form a conditioned weathered oil sand slurry; and subjecting the conditioned weathered oil sand slurry to gravity separation at a temperature of at least 50°C to form a bitumen froth product.
mixing the weathered oil sand ore with heated water and sodium triphosphate to form a weathered oil sand slurry;
adding sodium triphosphate to either the weathered oil sand ore, the heated water, or to the weathered oil sand slurry;
conditioning the weathered oil sand slurry at a temperature of at least 50°C to form a conditioned weathered oil sand slurry; and subjecting the conditioned weathered oil sand slurry to gravity separation at a temperature of at least 50°C to form a bitumen froth product.
2. The process as claimed in claim 1, wherein conditioning and gravity separation take plarp at himtwppn tn 80°C.
3. The process as claimed in claim 1, wherein the temperature of the gravity separation step is maintained at at least 50°C by adding heated water to the conditioned weathered oil sand slurry prior to subjecting it to gravity separation.
4. The process as claimed in claim 1, wherein the dosage of sodium triphosphate is at least 0.05 wt% per tonne dry oil sand ore.
5. The process as claimed in claim 1, wherein the dosage of sodium triphosphate is at least 0.1 wt% per tonne dry oil sand ore.
