Platinum Catalyst Supply Chain

What this topic covers

Mining, refining, catalyst manufacture, use, collection and recycling as one material system.

Core catalyst ideas

Platinum supply begins with primary mineral production and is supplemented by recycled material.

Catalyst manufacturers convert refined PGM into highly engineered products.

Collection and recovery link end-of-life material back into the supply chain.

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.
