Silver, gold and platinum group metal (PGM) thermal metallurgy generates sweeps, dross, slag and refractory waste with very high intrinsic value. Autocatalyst recycling is the dominant source of palladium and rhodium in the EU, with approximately 60 tonnes of PGMs recovered annually. Jewellery manufacturing generates bench sweeps containing gold, silver and platinum particles refined by assay and smelting.
Refinery slag from precious metals processing contains residual gold and silver values at 50–500 ppm requiring further processing or controlled disposal. Refractory bricks from induction furnaces used for gold melting absorb significant gold values over their service life, making brick recycling with assay and refining economically mandatory.
Chain of custody documentation is a regulatory requirement for precious metals waste management. REACH restricts certain platinum compounds in specific applications, and cyanide used in gold extraction from sweeps is regulated under IED with mandatory cyanide destruction before effluent discharge.
Typical Generators
Established valorisation pathways for EWC 10 07 08, ranked by economic value and market depth.
All precious metal-bearing waste streams are directed to LBMA-accredited refineries for assay, smelting and electrorefining. Gold is recovered to >999.9 purity, silver to >999 purity. PGMs are separated by solvent extraction or ion exchange to palladium, platinum and rhodium metal.
Spent furnace bricks are crushed, sampled and assayed to determine precious metal content before sale to refinery. Typical refractory from gold melting furnaces contains 100–2000 ppm Au recoverable by acid leach or smelting. Chain-of-custody documentation maintained from furnace removal to refinery settlement.
Slag fractions confirmed at <1 ppm precious metal content by ICP analysis are managed as non-hazardous inert waste and disposed to inert landfill or used as aggregate filler. Full analytical documentation required to demonstrate no economic recovery case before disposal is permitted.
These are the established routes for EWC 10 07 08. Which one your stream qualifies for depends on its composition, volume and region.
