Assay & Metal Accounting for Spent Catalysts
Why representative sampling matters when valuing recoverable platinum.
Industrial note: catalyst performance depends on the specific chemistry, reactor, feed and approved process conditions. This site explains system concepts rather than operating recipes.
What this topic covers
Why representative sampling matters when valuing recoverable platinum.
Core catalyst ideas
Precious-metal value depends on actual recoverable metal content, not original nameplate loading alone.
Spent catalyst can be heterogeneous because of wear, deposits and service history.
Commercial settlement systems depend on sampling, assay and contractual terms.
System tradeoffs
Representative sampling and assay are critical to metal accounting because spent catalyst is often heterogeneous.
Performance evidence
Recycling reduces primary-material demand but still involves collection, processing losses and energy.
Lifecycle perspective
Extraction and refining methods are hazardous industrial operations and are outside this site's procedural scope.
