As a professional manufacturer of precious metal recycling equipment, we provide complete sets of refining systems for recovering gold, silver, platinum and palladium from electronic scrap. Many new investors are easily attracted by exaggerated profit claims online and rush into this industry without sufficient technical knowledge, which often leads to heavy losses. Raw material cost, stable scrap supply, purchasing price and reliable equipment are the core factors that determine your project profitability.
E-waste precious metal recycling is a profitable business, yet it cannot be scaled up blindly. It requires steady technical support and proper equipment configuration. We offer modular solutions for small pilot workshops, medium-scale plants and large industrial production lines, helping customers avoid unnecessary investment risks and improve metal recovery rates.
Common Raw Materials with Recoverable Precious Metals
A wide range of electronic scraps contain valuable noble metals:
- Waste mobile phone boards, chips, connectors, battery contacts, SIM cards
- Scrap computer motherboards, CPUs, RAM modules, plugs and connectors
- Waste electroplating sludge and wastewater from precious metal plating factories
- PCB factory wastewater with gold or palladium
- Jewellery factory scraps, gold-plated aviation plugs, gold-plated electronic pins and components
- Silver-bearing waste: X-ray films, photographic fixer waste, silver contacts, silver-plated electronic parts, silver ceramic capacitors
- MLCC monolithic capacitors from mobile and computer boards (main palladium source)
- Waste colloidal palladium liquid and various precious metal-containing industrial residues
Our Equipment Portfolio for Precious Metal Refining
We design equipment according to your production capacity and raw material types, covering lab-scale test units to full continuous production lines.
✅ Small-scale / Pilot Test Equipment Glass reaction vessels, heating units, filtration sets, measuring cylinders, filter funnels, pH monitoring tools. Ideal for laboratory testing, formula verification and beginner trial runs. You can observe solution colour changes and metal precipitation clearly during testing.
✅ Medium-Size Production Units Acid-resistant plastic reaction tanks, filtering systems, heating & stirring assemblies, fume treatment devices. Widely adopted by small and medium recycling workshops for hydrometallurgical refining.
✅ Large Industrial Production Lines Enamel reactors, stainless steel tanks, shredding & grinding machines, gravity separation equipment, filter presses, smelting furnaces, waste gas and wastewater treatment systems. Our team can provide customized layout and engineering design for turnkey projects.
Typical Recovery Processes Supported by Our Equipment
Our systems support mainstream hydrometallurgical routes for noble metal extraction, matching your operation flow:
- Silver Recovery from Fixer Waste & X-ray Films Sodium sulfide precipitation to collect silver sulfide sludge, acid dissolution, impurity filtration, pH adjustment, zinc powder reduction to obtain sponge silver, then smelting into silver ingots.
- Silver Stripping & Recovery from Silver-Plated Parts Mixed acid stripping removes silver coating; silver is precipitated as silver chloride, then reduced by hydrazine hydrate to sponge silver.
- Gold Extraction from Gold-Plated Copper Components Nitric acid dissolves copper substrate, gold residues are filtered out. Gold is dissolved in aqua regia, followed by nitrate removal, filtration, then reduction by ferrous sulfate or sodium sulfite to get sponge gold. Final acid purification and melting produce high-purity gold ingots.
- Gold Recovery from CPU & Waste PCB Boards Disassemble PCBs, separate northbridge/southbridge chips with higher gold grade. Roasting, grinding, acid leaching, aqua regia dissolution, nitrate removal and chemical precipitation for gold powder.
- Palladium Recovery from MLCC Capacitors Roast and crush MLCC components, acid leaching, silver removal, nitrate elimination, pH adjustment with ammonia, palladium precipitate formation, hydrazine hydrate reduction to sponge palladium, then smelting.
- Colloidal Palladium Waste Liquid Treatment Heat demulsification to precipitate palladium sludge, acid dissolution and refining following standard palladium purification workflow.

Important Reminders
Precious metal refining uses corrosive acids and produces toxic fumes. Operators must follow safety protocols with ventilation systems and PPE. Local environmental and waste disposal regulations must be strictly complied with. Do not trust overstated profit propaganda. We recommend starting with small-scale testing to verify raw material grade and recovery efficiency before mass production.
