Recycling gold from computer parts
ATTENTION: Due to the large amount of spam and repeat questions in the comments I have decided to disable comments and instead to a write up in here about everything that was discussed.
First of all this was never about making money and is not a good way to make money, it was only to show the science. I did not do things in the cheapest way either.
Yes, a good idea would to wash the chip in nitric acid to dissolve any copper and silver away, then in aqua regia to remove the gold. You could also take that powder I ended up with and wash that in nitric. Either way, without doing that magnesium drops all the metals dissolved.
This was a very old ceramic chip, so there was not a whole lot of other metals on it.
Sodium metabisulfate is a better dropping reagent and is more commonly used. It is more selective and cheaper. I have had some trouble with it and as I said had no intention of making money so I just used magnesium metal.
Only CPUs contain recoverable gold as far as I’m aware. This will not recover gold from your HDD, motherboard, or any other component.
The HCl I purchased at Home Depot. The nitric acid was purchased from Elemental Scientific, and the bottle the nitric acid is stored in was purchased from HMS Beagle.
The reaction between magnesium and chloroauric acid is Mg + HAuCl4 = Au + MgCl2 + H2

Super Mario Bros. Special
Surprisingly rare game, known as Super Mario Bros. Special. It came out on the PC-8801, a computer made by the same company that made the Turbografx 16.
Nintendo had absolutely nothing to do with the production of this game, believe it or not. Hudson did everything.
The load time on the system I used was amazing. It took about 10 minutes to load, so I cut it down for you guys.
