Consider a mixture of Aluminum (cast materials, Sheets, sections), Magnesium, Copper, Iron, steel, Brass, Zinc, Rubber and Plastics. In this case what would be efficient?
Magnetic separation is the best and it will filter half the mess from the list. And all also we can separate the magnetic materials to a good deal as not all are attracted like Iron Brass and Copper.
The Non magnetic materials are really easy to sort as they can be dropped in water and plastics can be removed from heavier rubber.
Magnetic material can be sorted by passing a Jet stream of water which will wash away Lighter magnetic materials like alumimium and leaves only IRON and Brass for the finale
