Jiangxi Mingxin's Water-Based Separation Technology for Waste Circuit Board Recycling-Information-Jiangxi MingxinIn the field of e-waste resource utilization, the water-based separation technology for waste circuit board recycling developed by Jiangxi Mingxin Metallurgical Equipment Co., Ltd. has become a benchmark for green development in the industry, relying on its core advantages of environmental friendliness and high efficiency. As a high-tech enterprise with over 30 years of experience and numerous national patents, Mingxin has deeply integrated water-medium physical separation technology with its leading crushing technology, providing a solution that combines ecological and economic values for waste circuit board recycling.
Environmentally sound management is one of the core competencies of Mingxin's water-based separation process. Compared with the exhaust gas pollution and chemical residues caused by traditional recycling methods such as open burning and chemical soaking, Mingxin's water-based process uses water as the core medium to separate metals from non-metals through physical means, fundamentally eliminating harmful gas emissions and chemical pollution to soil and water bodies. Meanwhile, the equipment is equipped with a complete water circulation system, realizing efficient reuse of water resources without secondary discharge of wastewater. It perfectly conforms to the circular economy concept of "waste minimization, environmentally sound management and waste valorization", a feature that has enabled it to pass stringent environmental standard certifications and become a model for green recycling.
High-efficiency recovery and high-purity output demonstrate strong technological strength. Relying on the company's domestically leading waste circuit board crushing technology, Mingxin's water-based separation process first crushes circuit boards into an appropriate particle size with precision, fully dissociating metal foils from resin and glass fibers. Then, through a combined process of hydraulic separation and shaking table separation, it achieves accurate separation by utilizing the density difference of different materials. Data shows that the copper recovery rate can reach as high as 99%, the purity of metal concentrate exceeds 90%, and the purity of non-metallic tailings is over 95%. This not only surpasses the industry average level by a wide margin, but also maximizes the economic value of precious metals such as copper, gold and silver in circuit boards. At the same time, the separated non-metallic materials such as resin powder and glass fibers can be reused as construction raw materials, realizing the full-chain reuse of resources.
Stable and convenient operation experience as well as full industrial chain support further enhance the application advantages of Mingxin's water-based separation process. The entire set of equipment adopts a fully automatic process design, featuring simple operation, easy maintenance and continuous production capacity, which greatly reduces labor costs and operational difficulty. In addition, the equipment operates stably with excellent noise control, adapting to various production scenarios. Supported by the company's "industry-university-research" integrated innovation system and technical reserves endorsed by multiple scientific and technological awards, Mingxin can not only provide standardized water-based separation equipment, but also customize overall recycling solutions. Coupled with comprehensive technical support and globally recognized product quality, it helps customers build efficient and reliable recycling production lines.
