Rare-metal recovery from trace and difficult industrial waste
Separation and recovery of rare and precious metals from electronic substrates, exhaust catalysts and agro-pharmaceutical waste, including difficult waste and trace concentrations.
AI-assisted directory summary. Technical specifications, performance metrics, readiness and compliance labels are unverified unless individually supported and reviewed. Proposed partnership routes do not establish supplier consent, export eligibility, or willingness to sign an NDA. Confirm claims and test conditions with the linked sources and supplier before procurement or citation.
Problem solved
Recovers constrained metals from mixed or low-concentration industrial waste streams that are difficult to process with a single conventional route.
Application contexts
- Electronic-component manufacturing waste
- Exhaust-catalyst recycling
- Agro-pharmaceutical waste treatment
- Critical-mineral secondary supply
Technical principle
Combines carbonization, ashing, acid dissolution, resin adsorption, distillation and solvent extraction, selecting organic or inorganic chemical treatment according to the waste composition.
Typical use cases
- Recovery of indium and gallium from electronic-material waste
- Recovery of cobalt, nickel and tungsten from industrial waste
- Recovery of neodymium and dysprosium from magnet-related waste
Partnership route
How global engineering teams typically engage this asset.
Helpful to include: waste type and monthly volume · target elements and concentration · hazard classification · required recovered-product purity · chain-of-custody needs · sample analysis and pilot protocol
