Maybe i am wrong but if you melt your metals into bars, i think you may have a problem selling them to a scrap yard. They wont know if any other metal is in that bar. I know a few people have had the same thought with copper and brass and the answer is always the same. I wonder if anyone has tried this or asked their yard if they could sell metals in bar or ingot form? Have to remember to ask next time i go to the yard.
