Abstract
The use of seawater in mining/metallurgical operations seems to be the only sustainable solution in many zones with limited resources of fresh water. This requires new flotation technologies for processes which are to be carried out in highly concentrated electrolyte solutions. This paper reviews fundamental aspects of flotation in aqueous solutions with high concentration of inorganic electrolytes. Salt flotation, the process of flotation of inherently hydrophobic solids in concentrated electrolyte solutions, is especially suitable for theoretical analysis since no other organic agents are used in it. Starting from this example, the case of flotation of sulfide ores (chalcocite, chalcopyrite, pyrite and molybdenite) is discussed. The flotation of Cu-Mo sulfide ores requires the use of flotation agents, which are different for the inherently hydrophobic molybdenite and hydrophilic copper sulfides. The process is commonly carried out in alkaline pH adjusted with lime to depress pyrite, but in seawater depressing effect of Ca ions on molybdenite flotation is augmented, and different pyrite depressants are needed.

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
