Properties and Suitability of East Aqaba Area Feldspar for Glass Industries in Jordan
Bibliographic record
Abstract
In this study, a pegmatite ore with a Na2O/K2O (5.54-4.29) ratio of 1.29 was studied in a Denver flotation cell in which both at natural and acidic pH using HF and H2SO4. Because of the perthitic structure of the ore no significant separation is observed at natural pH. Interestingly, a selective separation was achieved at low pH using HF and H2SO4 (pH 2–3). a pegmatite ore composed of 5.53% Na2O and 4.29% K2O is upgraded to 10.51% Na2O and 6.59.02% K2O with a Na2O/K2O = 1.62 in HF medium and to 2.55 in H2SO4 medium. It is shown that products recovered in various stages are also considered as commercially significant; especially quartz which is recovered in the tailings in HF medium is suitable for glass industry.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
