Freon,
Take a look at Foam's previous posting. He has a setup that takes granulated material--usually wire--and drops it onto a vibrating table in combination with air separation. The vibrating table is set up at a slight angle so that heavy material moves one way on the table and the lighter materials move the other direction. This works pretty well for stuff like wire, where the density of the copper is 'way different than the insulation. He has posted a short video of it operating. If you are interested, do a google or youtube video search for "copper granulators". There's lots of vid's on the subject. There are quite a few machines on the market that do this. They are all pretty pricey, so it makes Foam's homebuilt efforts all that much more impressive.

I'm not so sure vibratory separation works quite as well with copper and aluminium. The video shows stuff that was shredded but if it was rads I don't think it was shredded fine enough for vibratory sorting. I'm thinking there might need to be a secondary granulating step to take it down a little finer.

Its cool equipment and I am hoping Foam will post more video's of it operating. I find it fascinating that you can shovel wire in one end of the machine and get fine copper granules from one output spout and fine bits of wire insulation out of the other. That's why I called it his money machine!! I'm sure it isn't quite that easy!!
