in planning my first trip ever to the scrap yard this week and i need some guidance on how sort my copper. i have a bunch of clean little copper tubes (out of window a/c units), a bunch of stripped braided wire, a bunch of stripped solid strand wire, stripped motor windings, and a few other clean copper pieces. do i have to keep it all sorted separately when i take it in? i just want to do it the right and get the most i can out of it. any help would be greatly appreciated. thanks
