ABSTRACT:
A method and apparatus for processing scraps by separating and recovering various nonferrous metals from a mixture of scraps comprising nonferrous metals and nonmetals, wherein scraps which have been crushed and cleared of magnetic substance parted from long-size material and washed out of the adhering fine dust and oily substance, and separated into light and heavy materials based on the difference in the specific gravity thereof by use of a heavy liquid made up of water and magnetic powder body and by the effect of an upward flow of the heavy liquid which increases its own apparent specific gravity; the separated light material is further sorted into nonferrous metals and nonmetals based on the difference in the electric conductivity thereof by the application of a moving magnetic field thereto, being recovered as resources.
