Abstract:China is the largest producing and consuming country of electrical and electronic products in the world. PCBs are the foundation of modern electronics industry. With the rapid upgrading and renewing of electronic products, the output of WPCBs increases. Based on the resource attribute of WPCBs, this paper makes a preliminary study into the process control of WPCBs smelting and does a systematic research on the optimization of top blown smelting refractories, which has been verified in practice and thus provides a new industrialization path for resource recycling of copper-based solid waste such as WPCBs.
