| description | PURPOSE:To reuse valuable metals in furnace bottom ash resulting from shredder dust as resources and to make furnace bottom ash harmless. CONSTITUTION:The furnace bottom ash 1 separated as small pieces in a separation process 2 is separated into magnetic matter 2 and non-magnetic matter 5 in a magnetic separation process 3 and the non-magnetic matter 5 is classified into oversize matter 7 and undersize matter 8 in a classifying process 9. The undersize matter 8 is further applied to a crushing process 9 and, after the glassy substance and molten matter in the undersize matter 8 are ground, the ground matter is classified into coarse particles 11 containing high purity copper refuse, fine particles 12 of a mixture of copper wires, granular glassy matter and molten matter and fine particles 13 containing glassy matter and molten matter in a classifying process 10. The fine particles 12 are dried and classified into conductive matter 14 and non-conductive matter 16 not almost containing a metal in an electrostatic sorting process 15. |
