this is concentrated nitric acid really nasty stuff especially when it's eaten up it'll dissolve practically all the metals from the circuit boards but it won't affect the gold in industry that extract the silver and copper from this but I've only got eyes for one thing gold but it still leaves us with the problem of separating the gold from all the undesirable rubbish that's in circuit boards which means unfortunately we're now gonna have to dissolve the gold it sounds like a gamble but I'm hoping it'll pay off in the end because gold is so unreactive I'm going to need some really powerful acid to dissolve it this is way beyond school chemistry and making up what medieval alchemists called aqua region or royal water it's a mix of very concentrated and strong acids strong enough even to dissolve gold if I get it right it shouldn't affect the other stuff the gold is mixed up with but it would happily burn right through my skin give him the chance a lot of mining processes involve some pretty nasty chemistry this is a bad as noxious as it gets for me with a bit of added heat all that gold I've worked so hard to get starts to vanish if I don't get the next stage of the recipe right it could be gone forever you look at that dirty black liquid I've just made difficult to be confident that it's full of gold it's a bit of a leap of faith another few minutes of stirring at gas mark 4 and we're done now I've dissolved my gold into a liquid all I need to do is pour it through a filter to separate the gunk from the good stuff I'm not sure about this I seem to have made pure green not gold no matter I should keep following the recipe add a pinch of urea quite Lively now comes the chef's secret ingredient what I'm about to do here is pretty much the alchemists dream I'm gonna make pure gold appear from something that isn't gold this is sodium metabisulfite nothing everyday compound for folk like me but chemists use it quite a lot what it's gonna do effectively is out a couple of electrons to that gold to turn it back to gold metal and it goes you've got a good stir I'm still not seeing any gold I'm gonna need more sodium metabisulfite lots more time to start getting a bit more freeform with the quantities [Applause] a little bit of gold panning later and I've reduced all the gold from my pile of circuit boards to this okay I've got myself there I'm a gold mud at the moment it looks a bit brown and uninspiring let's see what happens when I put a flame to it or perhaps two now I'm not gonna lie to you I don't hold out much hope for whatever is left in that tiny crucible...
