Aluminum Dust and Turnings

I did a search but didn't find anything on aluminum dust, just metal dust in general. I have 3 shopping bags from one clean up (we do it at least 3-4 times a year) of under the 2 saw we use at my work. They have enclosed bottoms so the dust is almost pure, just a little cutting oil and very little bit of wood from the occasional cut.

I know of one yard that will pay .40 for the turnings (didn't ask how small they can be) but is there anything I can do with the dust? We must throw out 100+ lbs of the stuff a year. If I start saving it, does anyone have any tips how I can separate the impurities and maybe even make my own ingots?

mix it with some iron shavings and water and make hand warmers for the winter time.

Almost forgot about this thread. I found out my yard buys the stuff for .20/lb. But, if that new section on smelting goes up, I might start hoarding it to make stuff at my dad's place in the fire pit.

It's not really dust, a lot of it is "turnings" I guess you would call it. And I didn't mean to make ingots, I'm thinking of making little statues and small items out of castings, so I won't really care how pure it is. Plus I get it for free and it's not really that much $$ at .20/lb.
