| Abstract: | This paper presents the method of recovering Fe and base metals, such as Cu, Al, Pb, Zn, Sn and Ni, from the printed circuit boards （PCBs） in the electronic wastes. The results show that the ferromagnetic metals that can be recovered by magnetic separation accounts for about 8. 23% of PCBs, while the metals and non-metallic substances can be effectively separated using the heavy liquid separation method. The recovery ratios of Fe, Cu, Pb, Zn, Ni and Sn in this process attain approximately 100%, 80%, 65%, 75%, 88% and 56%, respectively. |
