Abstract
The centrifugal separation process of mediate products from Clarabelle mill grinding circuit of Falconbridge-Sudbury Corporation by use of the Knelson Concentrator to recover the platinum group metals and gold is investigated.The results show that the platinum group metals and gold are selectively enriched in the milling discharge and hydrocyclone underflow,the excellent result for valuable metals recovery is achieved by the combination technology with the typical Knelson concentrator and the speed-variable Knelson concentrator.The general recovery and the grade as well as the rate of Pt,Pd and Au enrichment in the two-stage centrifugal concentrate from the milling discharge are 84.70%,56.39%and 80.50%; 137.67 g/t,54.27 g/t and 155.93g/t;49.6,31.9 and 47.7,respectively.The general recovery and the grade as well as the ratio of Pt,Pd and Au enrichment in the two-stage centrifugal concentrate from the cyclone underflow are 76.52%,49.93% and 77.79%;112.70g/t,47.86g/t and 120.81g/t;42.3,27.9 and,respectively

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
