Precious Metals Extraction Solution from Electronics

With the ever-accelerating pace of global electronic device upgrades, mountains of discarded circuit boards, mobile phones, and computer motherboards are piling up, yet the gold, silver, palladium, and other metals they contain are far from being fully recycled. Developing an efficient, safe, and stable precious metal extraction solution is not only a business opportunity but also a crucial way to improve resource utilization and reduce environmental burden.

Why is extracting precious metals from electronic waste so important?

While the amount of precious metals in electronic products may seem negligible, their accumulated value is astonishing. For example, the gold content in one ton of circuit boards can even exceed that of some ores, turning electronic waste into an "urban mine." Extracting precious metals through specialized processes not only recovers high-value metals but also allows for the classification and reuse of other materials, achieving a more complete circular economy chain.

The Complete Precious Metal Extraction Process: From Sorting to Refining

To obtain high-purity precious metals from electronic waste, a scientific recycling process must be established. The first step is pretreatment, including dismantling, crushing, and sorting. The core of this step is separating plastics, glass, metals, and circuit board substrates, laying the foundation for subsequent extraction. The process then proceeds to the chemical treatment stage, where precious metals are extracted from the complex substrate through hydrometallurgy, extraction, and precipitation. The entire process requires precise control of acid concentration, temperature, and reaction time to ensure high metal recovery rates and stable purity.

After the separation of precious metals, further refining is necessary to achieve industrial-grade or higher purity standards. The final product can then be reused in industries such as electronics manufacturing, jewelry making, and chemical catalysis, re-entering the production system.
