Abstract
Gallium plays a critical role in high-tech industries but faces supply risks. Improving the efficiency of recycling and utilization of secondary resources has become the most reasonable approach to addressing this. This study employs historical material flow analysis (2000–2019) to evaluate global and regional gallium recycling potential. The results indicate that gallium recycling remains underdeveloped, with three key opportunities identified: recycling gallium from primary production, new scraps, and old scraps. During 2000–2019, the cumulative amounts available from these sources were 239,760 tons, 3464 tons, and 955 tons, respectively, yet their recovery rates remain as low as 1.74%, 27.28%, and 0.84%, respectively. Regional analysis shows that the recycling potential and opportunities of gallium varies significantly across China, America, the EU, Japan, and the rest of the world. Current recycling technologies have shown potential for efficiently recovering gallium, but their economic viability relies on economies of scale and policy incentives.

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
