Abstract

fetched live from OpenAlex

The ongoing generation\nof mature fine tailings (MFT) or fluid fine\ntailings (FFT) from surface mining activities of the oil sands industry\nin Canada has been a contentious issue for many years. In the absence\nof large-scale processing facilities, many far-reaching consequences\nfrom extensive stockpiling of FFT will plague the industry for many\nyears to come. Application of polymeric flocculants to treating FFT\nfor efficient solid–water separation has been well-established.\nHowever, most commercially used flocculants carry a negative charge\nand yield incomplete capture of suspended fine solids and hence relatively\nturbid recycle water. This inefficient flocculation of fine solids\nlimits the effort of process water recycling and severely strains\nmost downstream dewatering processes, such as filtration. Cationic\nflocculants offer a promising alternative in terms of overall solids\ncapture and recycle water quality, although the associated high cost\nhindered much of its commercial applications. In this work, we introduce\na method to deploy a commercial cationic flocculant (Zetag 8110).\nHeating and increasing pH of the flocculant solution in oil sands\nprocess water led to more effective fines flocculation and a supernatant\nof <200 nephelometric turbidity units (NTU), at ∼75% less\ndosage than the direct use of Zetag solution without any form of preconditioning.\nThe insights gained from this study can lead to a better flocculant\ndesign, utilization, and process economics for FFT treatment.

Teacher imitation

Not 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.
