Steam is injected into the oil sands deposit, reducing the viscosity of the bitumen. A mixture of mostly bitumen and water is pumped to the surface, where the water is recovered and recycled. The deposit is mined and trucked to a main processing plant. Hot water is added to the oil sands, producing a pumpable slurry.
