That's getting harder and harder with the price of scrap lead at insane levels, They're getting good money for it from the scrap guys who show up and pick up every week. The big chains actually dispose it "in house" - I know for a fact that Costco and Sears both do it this way.

Even if you can heat your alloy to 1200F, syou shouldn't even think of doing it. That's 300F beyond th red line of danger to your health and your life.
Personally, I don't understand why you want to remove tin. Tin doesn't actually make the alloy significantly harder - it mainly aids in mold fillout in low percentages (about 2%, beyond that it's a waste). Antimony I couuld understand, as it makes in significantly harder, especially if this is for a smokepole, but even then, you should "try and see". You may find it works as is.
$1.50 isn't "retail". It's actually a decent price. That commodity price? That's in 20 ton lots. "Retail" for lead right now is about 4 bucks a pound, plus shipping, in large pigs - McMaster has 60 pound pigs for $230.
