So, I suppose just do a round of heatings, first to 800F, strain out zinc.  then to 1702F strain out germanium, then to 1760F strain out silver, then to 1981F strain out copper. . .

Yeah pretty much this, being very careful on the temps.

I think the graphite crucible will work but I'm pretty sure that charcoal wont be hot enough. I'd try some sort of gas torch.

I have a very large setaline torch, that should work, right?

Acetylene?

I think so. Although it may be tough to do anything with platinum since that is about the maximum temperature of the flame itself (or so I read).

You do need a way to measure the temperature of the mixed metals so you can achieve the ideal ones, and keep the temperature steady until you are thru with the process. That shouldnt be too difficult though.

Ya, that's the one.  My spellings garbage. . .I always say it as set-a-lean, so that's about how I spelled it

About the temperature, I'm sure i could think of something.  Oh, and as far as copper goes, pre 1982 pennies are worth more in copper (almost .03c)

I've got hundreds of pounds of copper, it's mighty hard to get rid of them at more than 1.4x face. Things are worth what people will pay, and people won't pay 2 cents. At least yet.

What I mean is, If I melt the pennies, I might be able to get more. . .

Get some price quotes from scrap dealers in your area first. You'd be surprised how little they pay vs. spot price.

I would imagine if I refined the metal myself that I could get higher scrap price. . .but I get over half spot for aluminium  .50 a lbs, spot is .92

There is a melt ban on pennies.

You think refining your own is worth the startup costs and health risks?

I thought the point here was to make new coins, not melt down and save old ones.
