A Technical Exchange for Metal AI Builders
Built for metallurgists, process engineers, researchers, data scientists, plant teams, students, and AI builders. Trending discussions, open research questions, dataset requests, and monthly challenges, all organized by metal, process, and topic.
Monthly challenge
July: improve the rare earth recovery baseline
Beat the reference MAE on the open split. Reference and research submissions welcome.
- Open research question6123
Which features most improve stage-loss attribution in SX trains?
On the synthetic separation set, adding phase-ratio dynamics beat static pH features for attributing loss to a stage. Curious what others have found on real circuits.

Looking for anonymized aluminium scrap assays with cast-quality labels
Happy to contribute synthetic augmentation if anyone has non-confidential scrap stream assays paired with downstream quality outcomes.

Proposal: add calibration to the lithium impurity-risk benchmark
ROC-AUC alone rewards ranking, not calibrated probabilities. For a qualification decision, Brier + reliability should be first-class. Draft rules attached.

Slag chemistry features that generalize across furnace types
Fe/SiO₂ and magnetite indicators transfer reasonably; absolute temperatures don't. Anyone normalized furnace features across configurations?

Oxygen thresholds for qualification: one global cut or per-alloy?
The reference classifier uses a configurable threshold. In practice we set it per alloy family, so should the benchmark reflect that?

How far do tabular baselines get us before physics-informed models pay off?
Across the recovery benchmarks, gradient boosting is within a point or two of fancier models. Where does physics-informed structure actually earn its keep?
