Separation of Non-ferrous Metals in Automobile Scrap by Means of Permanent Magnets.
For Reference Only At Bureau Libraries :87 pages
The application of eddy current separators using permanent magnets to the processing of automobile scrap was investigated using ramp- type and rotary-drum metal separators. Such separators can serve useful functions in the scrap processing industry by beneficiation of nonmagnetic shredder outfall prior to shipment to central processing plants for further refinement and beneficiation of the aluminum concentrate generated by heavy media separators through removal of nonmetal particles. The segregation of different metals by eddy current techniques was also investigated. Positive segregation of aluminum from zinc does not appear possible, whereas segregation of lead and stainless steel from the zinc concentrate of heavy media plants appears feasible.
