Abstract:This paper describes the production practice of co-processing waste circuit board with top-blown smelting in Daye Nonferrous Metals Group Holding Co., Ltd. The magnetic separation and three-stage eddy current separation are used to separate the waste circuit board after crushing, and the removal rate of iron and aluminum reaches 95%. The maximum capacity of co-processing the waste circuit board can reach 10 t/h, and the metal recovery is higher, which has good economic benefit. The top-blown smelting furnace is unique in furnace condition, with the “3T” principle of controlling dioxins in the design of waste incineration treatment, which meets the requirements of environmental protection.
