Copper Slag Loss Predictor
Predicts copper losses to slag from furnace conditions, matte grade, and slag chemistry.
This model is a reference implementation. Industrial use requires validation on plant-specific data. Customer-specific fine-tuning remains private unless explicitly approved for publication.
Input schema
| Field | Type | Description |
|---|---|---|
| matte_grade | float · % | Target matte grade |
| slag_chemistry | float[] | Fe/SiO₂, magnetite indicators |
| furnace_conditions | float[] | Temperature, oxygen enrichment |
Output schema
| Field | Type | Description |
|---|---|---|
| cu_in_slag | float · % | Predicted Cu loss to slag |

Reproduced the reported metric on the public split with a fixed seed. Numbers line up within noise, so it's a good baseline to build on.

Adding an uncertainty head would make this far more useful for prioritization. Happy to open a PR against the reference repo.

Validate on your data, keep the result private
Reference models are a starting point. We can fine-tune privately on plant-specific data, with customer-owned IP and no public disclosure.
