Recovery Yield Concepts
Material accounting from spent catalyst to recovered PGM without extraction instructions.
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
Material accounting from spent catalyst to recovered PGM without extraction instructions.
Core catalyst ideas
Recovery yield compares recovered metal with measured metal entering the recycling process.
Sampling uncertainty and process losses both affect reconciliation.
High apparent recovery cannot compensate for biased sampling.
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.
