Mobility of elements from cesium formate residue emplaced on pegmatite tailings, Bernic Lake, Manitoba, Canada
Bibliographic record
Abstract
A Cesium Products Facility (CPF) at Bernic Lake, Manitoba, manufactures a Cs-formate drilling mud from pollucite (CsAlSi2O6•H2O) ore. The waste residue is dry-stacked over pegmatite tailings. This thesis studied the mineralogy of the residue and tailings, and the mobility of residue related elements: Ca, Cs, Rb, S and Sr. Major minerals in the residue include gypsum, quartz, barite, spodumene, feldspar, pollucite, and Cs-sulphate, and in the tailings, quartz, feldspar, spodumene, pollucite and micas. The residue contains an order of magnitude more Cs (<2 wt. %) than the tailings (<0.3 wt. %), with 47 % being mobile from Cs-sulphate and Cs-carbonate. Cs in the residue is immobile in microcline, pollucite, Cs-formate, and Cs in Fe-oxy-hydroxides. Elements from the residue are mobilized by water from several sources: meteoric water and surface runoff from the residue pile, precipitation leaching through the residue pile into the tailings, and direct contact of residue with groundwater.

How this classification was reachedexpand
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.
