DOES THE HYDROPHOBICITY OF POLYACRYLAMIDE COPOLYMERS AFFECT THE FLOCCULATION OF OILS SANDS TAILINGS?
Bibliographic record
Abstract
Oil sands mature fine tailings are stable suspensions of clay particles and residual bitumen that consolidate and dewater very slowly. This work selected a series of amphiphilic copolymers of acrylamide with comonomers presenting different hydrophobic chains (butyldiglycol methacrylate, 2-dimethylaminoethyl methacrylate, n-butyl methacrylate, and n-octyl methacrylate) and used them to flocculate and dewater oil sands tailings. It analyzes the influence of molecular weight, hydrodynamic volume, and hydrophobicity of these polymers on their flocculation and dewatering behavior using initial settling rate, supernatant turbidity, capillary suction time, and solid sediments content. The performance of these novel amphiphilic copolymer flocculants depended mostly on their hydrodynamic volumes and on their degree of hydrophobicity.

Full frame distilled prediction
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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
