Waste electric and electrical equipment recovery and utilization is highly regarded both in the whole country and in the recycling industry. Many large-scale dismantling and processing enterprises have emerged, which greatly promote the development of recycling industry, and laid a good foundation for further deep processing. A research was made on silver electrolysis technology and process control techniques in precious metals recovery. Combined with on-site management, this technology has applied in real production, and got good results.%报废电子电器产品的回收利用受到国家与行业的高度重视。大型拆解加工企业如雨后春笋般涌现，为后续深加工利用奠定了良好的基础，极大地推动了行业的发展。针对目前国内贵金属回收中粗银电解技术与过程控制技术的不足进行研究，将技术与管理有机结合起来，并在企业生产上予以实施，效果良好。
