METHOD FOR RECYCLING NOBLE METAL FROM ELECTRONIC WASTE MATERIAL AND APPARATUS THEREOF |
摘要 |
A method for recycling noble metals from electronic waste materials and apparatus thereof. The method comprises the following steps: mechanically breaking up the electronic waste materials; removing rubber and plastic materials by electrostatic separation; removing ferromagnetic metals by magnetic separation; removing residual rubber and plastic materials by microwave pyrolysis; removing low-melting-point metals by indirectly heating using microwave; separating the noble metals from one another in turn from low-melting-point metal to high-melting-point metal for recycle. The apparatus includes a microwave housing. A filtering screen is positioned on the inside wall of the housing horizontally, and vertically-arranged and open-ended heating pipes are positioned over the filtering screen. The method and apparatus can adequately recycle resources in the electronic waste materials. |
