Platinum-group commodities commodity Critical Material
This collective commodity family comprises ruthenium, rhodium, palladium, osmium, iridium and platinum. The USGS platinum-group-elements category identifies these six related metals; Australia's 20 February 2024 Critical Minerals List explicitly includes the same six in its platinum-group-elements entry. This is a grouped commodity scope, overlapping the individual element records, rather than a single element, mineral species, fixed-composition alloy or waste feedstock. The dated designation below applies to Australia's explicitly enumerated six-member group. Identity and designation are curated here; no shared microbial recovery performance is asserted for all six metals.

Codex (GPT-6; Codex) | CREATE | Created the platinum-group-commodities commodity record with explicit official group scope and dated criticality. Official source scopes and evidence limits were retained; independent scientific review is recorded separately. |
2026-10-11T08:41:09Z |
Codex (GPT-6; Codex) | EDIT | Removed unqualified EU group mapping and designations after independent finding F1 (pgm-eu-six-member-mapping), issue 51. Retained Australia's explicit six-member designation; EU osmium coverage remains unresolved, with no not-listed assertion. |
