Precious metals including gold, silver, palladium, platinum and rhodium are scarce strategic resources. Primary mining consumes massive energy and causes severe ecological damage. With the rapid expansion of global electronics, electroplating, auto catalyst and jewelry industries, large volumes of precious metal-bearing waste are generated, such as waste PCB boards, electronic components, electroplating wastewater, spent catalysts and precious metal scraps.
Our precious metal recovery equipment separates and purifies gold, silver, palladium, platinum and rhodium from waste materials through physical separation, hydrometallurgical extraction, electrolytic refining and smelting, producing high-purity recycled precious metals.
Core Benefits
- Resource Conservation: Reduce mining of virgin precious metals and realize circular reuse of precious metals from industrial waste.
- Higher Profitability: The production cost of recycled precious metals is much lower than primary smelting. Waste turns into valuable assets and improves project revenue for recyclers.
- Eco-friendly & Regulatory Compliance: Full sets of supporting gas and wastewater treatment units reduce heavy metal contamination, complying with waste & hazardous waste regulations in Europe, Southeast Asia, America and other regions.
- Industrial Chain Promotion: Cover waste pre-treatment, concentration, extraction, refining and ingot casting to support the whole recycling industry.
- Global Policy Support: Countries worldwide promote circular economy and extended producer responsibility, bringing continuous growth for precious metal recycling market.
Process Flow of Precious Metal Recovery
- Sorting & Pre-treatment: Waste classification, crushing, grinding, screening, gravity separation and electrostatic separation to enrich precious metals.
- Leaching & Concentration: Selective leaching to dissolve precious metals and separate base metal impurities.
- Precious Metal Extraction: Electrolytic recovery and cementation units to precipitate crude gold, silver, palladium and platinum.
- Refining & Purification: Electrolytic refining system to produce high-purity precious metals up to 99.99%.
