Driven by the rapid upgrading of the global electronics industry, consumer electronic products such as smartphones, laptops and home appliances are being updated at an increasingly fast pace, generating massive volumes of waste electronic resources. Discarded PVC circuit boards, previously treated as ordinary electronic waste, are now widely recognized as high-value “urban mines” rich in gold, silver, copper, tin, palladium and other precious and non-ferrous metals. With outstanding recycling potential and economic returns, waste circuit board precious metal recovery has become a high-growth, profitable green industry worldwide.
Industrial recycling data verifies the considerable economic value of waste PVC circuit boards. Typically, one ton of waste electronic circuit boards can yield approximately 350 grams of gold, 2 kilograms of silver, 120 kilograms of copper and 25 kilograms of tin, alongside recyclable palladium capacitors, nickel components and bare circuit boards. Electronic factory PVC offcuts and production scraps deliver even more remarkable precious metal recovery benefits. Supported by the enormous output of the global electronics manufacturing sector, waste PVC circuit boards and electronic scraps feature abundant, sustainable and stable raw material supply, ensuring long-term operational viability for precious metal recycling enterprises across the globe.
Specializing in international-grade wet metallurgy recycling technology and equipment, Henan Yusai Precision Machinery Co., Ltd. provides one-stop, turnkey wet-process precious metal extraction solutions for PVC circuit boards and photovoltaic panel waste. We have developed a fully optimized, eco-friendly and high-efficiency recycling system tailored for various electronic waste materials. Adopting advanced combined technologies of full dissolution and selective dissolution, integrated with activated carbon adsorption, precision refining, low-temperature drying and vacuum smelting, our complete production line enables stable and efficient gold and silver recovery from circuit board materials of varying grades. All final precious metal products meet and exceed international purity standards with consistent and reliable quality.
Compared with outdated traditional methods such as open burning and strong acid corrosion, Yusai’s integrated extraction technology and equipment deliver comprehensive technical and environmental advantages. The entire production workflow is standardized, streamlined and highly automated with simple operational procedures, effectively resolving the common drawbacks of conventional recycling: severe pollution, high energy consumption, low metal recovery rates and complex manual operation. Our equipment features strong universal adaptability for both high-grade and low-grade electronic waste and PVC scraps. With compact structure, low capital investment and no complicated infrastructure requirements, the production system supports fast installation, rapid commissioning and continuous large-scale industrial production, making it highly suitable for medium, small and individual recycling enterprises globally.
To maximize resource utilization efficiency and product purity, Henan Yusai Precision Machinery Co., Ltd. has independently developed exclusive high-efficiency gold and platinum refining agents. These proprietary additives significantly enhance extraction accuracy, achieving a precious metal recovery rate and final purity of nearly 100%. In addition, our whole-line closed-loop production design eliminates random emissions of harmful gas and wastewater. All process water is treated and recycled for reuse, achieving fully compliant, environmentally sustainable industrial production.
Our recycling system realizes full circular utilization of all waste resources. The residual slag after precious metal extraction contains no hazardous substances and can be proportionally blended with construction aggregates to produce eco-friendly bricks for building wall materials. Filtered PCB powder can also be reused for craft manufacturing. The entire process achieves zero solid waste discharge, completely avoiding the environmental damage caused by traditional electronic waste disposal methods.
Beyond core wet-process extraction technology, our modular equipment supports multi-process compatibility, including electrolytic refining and separation technologies. We provide customized turnkey production solutions based on clients’ raw material types, processing capacity and finished product requirements. Featuring superior environmental performance and outstanding economic benefits, Yusai’s electronic waste recycling systems can extract dozens of kilograms of high-purity gold from hundreds of tons of electronic waste materials, delivering substantial investment returns. Our solutions empower global clients to achieve standardized, green and profitable precious metal recycling, standing as the ideal industrial solution for modern electronic waste resource recovery worldwide.
