Enhanced settling of fine silica by direct AC electrocoagulation
Bibliographic record
Abstract
Ground silica (d50, 20 μm) was treated as an aqueous suspension of 5·0 wt-% solids by alternating current electrocoagulation (AC/EC) in the direct mode. The initial settling rate increased linearly by 0·054 m h−1 per minute of AC/EC, with the maximum (>7·32 m h−1) occurring at t>120 min of AC/EC. Up to 75 min, floc size controlled the initial settling rate; at longer times, floc morphology took control.Aluminium released from the electrodes was adsorbed as it entered the pulp, and could be viewed as having been metered in continuously. Aluminium precipitation became prominent after ∼75 min of AC/EC time and was not deleterious to the enhancement of settling behaviour.Two years after its preparation, electrocoagulated silica was demonstrated to be an effective coagulant for as-received silica and oil sands fluid fine tailings.

How this classification was reachedexpand
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.
