Kieserite Solubility in the Aqueous FeCl<sub>3</sub> + MgCl<sub>2</sub> + HCl System between (338 and 378) K
Bibliographic record
Abstract
Kieserite (MgSO 4 ·H 2 O) solubility was measured at temperatures between (338 and 378) K, FeCl 3 concentrations of 1.0 mol·kg −1, MgCl 2 concentrations between (1.1 and 3) mol·kg −1, and HCl concentrations between (0.5 and 2.3) mol·kg −1 . These conditions are of interest because of their relevance for processes designed to extract nickel from oxide ores by atmospheric leaching in mixed sulfate−chloride solutions. Experimental data were compared with model predictions generated by use of OLI Software’s mixed solvent electrolyte (MSE) model. Model predictions for MgSO 4 ·H 2 O solubility were found to match experimental results with an average absolute deviation of ± 0.09 mol·kg −1 and an average absolute relative deviation of 11.1 %. The ability of the model to accurately predict solubility trends in solutions not used in the development of model parameters validates the model.

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.
