Abstract
Two frothers covering a very broad range from weak and selective (DF-200) to powerful (DF-1012) flotation performance were chosen to test the effect of frothers on bubble generation and bubble coalescence in a laboratory scale flotation cell. In two-phase, gas-liquid systems, the experiments showed that the frothers affect both the bubble breaking process and the coalescence of bubbles. While the DF-200 frother, characterized by much larger critical coalescence concentration (CCC) values than DF-1012, has the ability to produce finer bubbles at concentrations exceeding the CCC value, the bubbles generated in the DF-1012 solutions at concentrations exceeding CCC are much larger. On a retenu deux agents moussants couvrant une vaste gamme, allant d'une performance de flottation faible et sélective (DF-200) à puissante (DF-1012), afin de tester l'effet des agents moussants sur la production et la coalescence des bulles dans une cellule de flottation à l'échelle de laboratoire. Dans des systèmes gaz-liquide diphasiques, les expériences montrent que les agents moussants influent à la fois sur le processus de rupture des bulles et la coalescence des bulles. Alors que l'agent moussant DF-200, qui se caractérise par des valeurs de concentration de coalescence critique (CCC) beaucoup plus grandes que pour le DF-1012, a la capacité de produire des bulles fines à des concentrations excédant la CCC, les bulles produites dans les solutions de DF-1012 à des concentrations excédant la CCC sont beaucoup plus larges.

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 it
