It all depends on who you are selling your metal to, and how they are set up to check the composition of the metal.
For precious metals it's a no brainer, you recover, refine, cast into bars and sell it for more than otherwise you could.
For other metals, it depends. Most scrap yards do not seem to be equipped to analyze metal composition. This is why most scrap yards don't accept ingots. If you find a scrap yard that uses an XRF gun to test metals, they will probably take your bars. However, if you skip the scrap yard all together and take your bars directly to the end user, like a foundry or refinery they will not only be able to take your bars, but you will have removed a middle man and make more from all your hard work and labor.
I'll use this as an example because I actually know a couple that went into the recycling business who did exactly this. They started accepting cans at a location, that's all they started doing, 4 years ago. The husband decided, because the cans are bulky and took up a lot of room in their small location, that melting the Al and casting into bars would better serve their purpose. They could make fewer trips to the people they sold the Al to because they were able to load far more in Al bars than cans. In they state they live in, they pay the recycle value their state government has set for Al cans. Once melted into bars however, the metal is worth more, it's sold as clean Al instead of cans.
Generally speaking you can get around .50 cents per lb on Al cans. You can get over $1.00 dollar per lb on ingots.
So if you spend the little extra time, sell to the right people, you can make twice your money just on Al cans.
The couple I am using as an example did exactly this. They now have a 15,000 sq ft facility and are repurposing, remarketing, and recycling all kinds of metals and machinery. They landed a big Land-O-Lakes account and are doing very well for themselves. When you talk with them, they both will say it's because they started casting Al ingots and selling them for more.
So to answer the question is it smart? If you are able to sell directly to the end user, and remove the middle man, that's is always smart, you make more profit. Casting metals into ingots and selling to the correct end user, smart, you will make more money. Is it feasible? Only if you live in an area where there is an end user, a foundry or refiner who is close enough to make it cost effective to truck it to them, and skip the scrap yard.
I imagine the next question would be "who to sell to" I would google people in your area who purchase scrap, ingots, are foundry or refiner who also have the ability to analyze your ingots either by XRF or ICP, etc. Many scrap yards now also lease XRF units to check for alloy composition so I wouldn't totally discount them. If you cannot find a foundry or refiner close by, scrap yards that can analyze your metal composition should pay more for ingots just because they get more for ingots.
And as one person has already mentioned, if you are melting and pouring, might as well go one step further and cast something artistic or useful, you will get far more taking your item from recycle to retail product than you would selling as scrap. You wouldn't have to scrap so much, and would make more money in the long run. That's what I do with a lot of the precious metal I recover and refine, I turn it directly into retail products and sell sometimes, for twice the actual value of the metal.
Anyway, that is my two centavos. I hope it helps
