Metal Extraction

#1  Postby LjSpike » May 12, 2016 4:11 pm

I've got my AQA C1 chemistry exam in a week, and was going over metal extraction, with electrolysis and displacement with carbon and so forth. Now I had an idea, its probably incredibly flawed as I haven't researched into it too far, but surely you could just perform a kind of system like this:
1) Displace copper with lead
2) displace lead with tin
3) displace tin with iron
4) displace iron with zinc
5) displace zinc with aluminium (I know, i could use carbon.)
6) electrolysis on aluminium

you then have all 6 of your metals in pure form.

Did you check the reduction potentials for your metals to see that you're not going to wind up with more than one metal being reduced at each step? Because I'm not entirely sure you got that in the correct order.

You possibly could displace metals that way (see SS's post), but it wouldn't be economical.

To be fair, frictionless surfaces aren't all that economical (or realistic), either. But they showed up in my physics homework A LOT!
