Abstract

fetched live from OpenAlex

Abstract The RM (Li, Be, Ti, Zr, Nb, Ta, Th and U) and REE (Light Rare Earths and Heavy Rare Earths including Yttrium) are strategic and critical for sustaining a variety of industries such as nuclear, defence, information technology (IT) and green energy options (wind, solar, electric vehicles and others). The 2010 ‘Rare Earth’ crisis of the world, following China’s monopoly with over 80% share and export restrictions in the REE market, led to an exploration boom for REE all over the world including India. This led to a substantial increase in REE mineral resources (98 Mt of contained REO in 2015) outside China located in Canada (38 Mt), Greenland (39 Mt) and Africa (10.3 Mt) that represents a five-fold increase in resources (c.f. Paulick and Machacek, 2017). As per the 2019, USGS commodity survey, the world reserves of REE have been estimated at 120 Mt in countries such as China (44Mt), Brazil (22Mt), Vietnam (22 Mt), Russia (12 Mt), India (6.9 Mt) and others (13 Mt). At present world resources of RM and REE are adequate to cater the demands of the different industries. The constraints, however, appear to be not technical but mainly environmental and social issues.

Full frame distilled prediction

Teacher imitation

Not 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.
