Final Products

Our equipment and recycling technology can recover rare metals such as gold (Au), silver (Ag), palladium (Pd), platinum (Pt), rhodium (Rh), and ruthenium (Ru), with a recovery rate of over 99% and a purity of 99.99%.

Working Process

Precious metals refining plant recycling process begins with smelting reduction and oxidative smelting inside intermediate frequency and converting furnaces. The resulting precious metal alloy blocks undergo water atomization (shotting) for fragmentation to prepare them for subsequent refining. Next, the fragmented alloy passes through hydrometallurgical extraction to achieve the separation and high-purity refining of various precious metals.To ensure environmental compliance within the workshop, all localized exhaust emissions must be equipped with dedicated ozone-based gas scrubbing systems. Additionally, all locally generated process effluents must be managed via a tailored tail-liquid collection and guiding system. This setup channels all residual liquids directly to the wastewater treatment plant, ensuring they are either safely discharged or reused only after fully meeting regulatory discharge standards.

PART 1: Through carbonization, non-metallic components such as plastics and resins are removed. After cooling, the materials are ground to facilitate the subsequent extraction process.
PART 2: After carbonization and grinding, the material enters the hydrometallurgical system for precious metal extraction.
PART 3: Through multi-stage separation, refining, and reduction, the precious metals are efficiently recovered.
PART 4: Wastewater can be discharged in compliance with environmental standards after proper treatment. The recovery rate of precious metals such as gold, silver, palladium, and platinum can reach as high as 97-99%.
Featuring a short processing cycle, the system utilizes a cyanide-free and eco-friendly hydro metallurgical process, effectively minimizing environmental impact.

Machine Features

1. Zero Increase in Wastewater Discharge:The refined process ensures that the post-treatment wastewater discharge volume remains unchanged, minimizing water consumption through advanced recycling.

2. High Recovery Rate & Exceptional Purity:The system achieves a recovery rate of over 99% for Gold (Au), Silver (Ag), Platinum (Pt), and Palladium (Pd), with the final precious metal purity reaching up to 99.9%.
3. Fully Automated Operation:Integrated with a fully automated control system, the equipment eliminates manual intervention throughout the process, significantly reducing labor costs and operational risks.

4. Resource Recovery from Off-Gas (Value Creation):The innovative off-gas treatment system converts emissions into valuable chemical raw materials (by-products), turning waste into wealth and generating secondary economic benefits.

5. Smart Off-Gas Compliance:Equipped with a fully automated monitoring and control system, the emission purification process guarantees strict compliance with national environmental protection standards.
