Abstract
To facilitate the optimization of and/or design of zinc electrowinning reactors, certain properties of zinc electrolytes, which are functions of electrolyte composition and temperature, have been investigated through a literature review that has been complemented, where applicable, by theoretical calculations. A new set of Pitzer model parameters has been determined for ZnSO 4 −H 2 SO 4 −H 2 O solutions from an examination of isopiestic data. Empirical correlations for zinc electrolyte conductivity, absolute viscosity, and density have also been examined. An expression for predicting the diffusion coefficient of zinc ions in acidic zinc sulfate solutions was also developed.

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
