Electrochemical Studies on Heazlewoodite Flotation from Inco Matte
Bibliographic record
Abstract
Electrochemical and flotation studies were conducted on Inco matte, composed of chalcocite (Cc), heazelwoodite (Hz) and Cu- Ni alloy. After magnetic removal of the alloy, the Cc is floated using diphenyl guanidine. There is some flotation of heazelwoodite due to inadvertent activation by Cu ions. This was investigated by rest potential measurements on matte components and mild steel, detection of Cu ions by EDTA extraction, and flotation. Rest potentials at pH 11.9 showed the order: Cc>mild steel>Cu-Ni alloy>Hz. Along with Cc, the Cu- Ni alloy is potentially galvanically active, releasing Cu ions. Sodium dithionite proved the most effective, reducing the rest potential and Cu ion release. Subsequent flotation, however, required aeration to restore Cc floatability. The need for aeration is compatible with the proposed surface product formed by reaction between Cu and DPG.

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.
