I don't sell my recovery's to scrap yards or other dealers.
My plan is to process all of these things my self.
I'm not a fulltime scrapper, just scrapped a few bits of junk lying around (my grandfather was a hoarder so I have a vast supply).
Once I've refined my techniques, I plan to use many of the elements that I recover for science projects.
Though I have a few ideas about becoming more of a serious scrapper/refiner and buying others scrap recovery (eg tantalum capacitors, etc).

I do sell brass to the scrap yards, as the price is good, and I've no use for it except a few little craft projects. Mostly I do a swap for Alpha brass and German Silver (type of brass) that is the size I need.
Except the copper, copper is quite easy to recover in a rather pure state.
I've a way to process it with zero cost into bars, and if I can get tonnes of it, then I can get $NZ10/kg shipping it to china (99% pure).
(the best local supplier pays $7.80, but many pay about $6ish)

Currently I don't bother with Iron, Stainless, Alumium. As they're just not worth it.
In the future I've a few ideas for the Alumium though which could make it worth my while.
