Abstract
Water-based bitumen extraction technology from mineable oil sands faces major challenges of high water usage and tailings disposal. In the present study, a process for solvent extraction of bitumen from Athabasca oil sands was investigated. In this process, oil sand is mixed with light hydrocarbon solvents, and the solvent–bitumen solution is separated from the mineral solids by centrifugal filtration or regular pressure filtration. The solvent left in the filtration cake is recovered by evaporation under vacuum at room temperature. The results show that, for both high-grade and low-grade ores, using appropriate solvent, the bitumen recovery and product quality are comparable to those from the currently used hot water extraction followed by naphtha froth treatment. The recovery of light hydrocarbon solvent is relatively easy, so this novel process has great potential to reduce solvent losses compared to existing technologies.

Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
