I will detail a process of turning old computer parts into little round lumps of pure gold. There are many places on the internet that offer such tutorials. I have seen some of these process and they talk about using such chemicals as Cyanide, and Mercury for chemical recovery. I assure you these chemicals are not required.
a Side cautionary note, This process is not suitable to purify Panned Gold or CARAT gold.
But this can be used on any GOLD plated or pure gold object.
THIS SHOULD ALSO NEVER BE ATTEMPTED INDOORS.

In this instructable you will be working with basic house hold chemicals. By themselves these chemicals can be fairly harmless. The combination of such chemical which will be presented in this instructable can be EXTREMELY hazardous; By such there are a couple of safety items which are not Optional. THE FOLLOW ITEMS ARE REQUIRED. FAILURE TO OBTAIN THESE ITEMS BEFORE HAND CAN POSSIBLY COMPROMISE YOUR HEALTH.
Item # 1.
Breathing equipment. You will need a chemical mask rated AT LEAST as a P100. If you dont know what a P100 rating means It is your responsibility to yourself to find out.
Item # 2
Heavy duty Gloves. pvc or rubber is fine, DO not use Latex or Nitrile gloves.
Item # 3
Safety Glasses. Any pair will work as long as It is safety rated and solvent rated.

i have just posted a question about gold leaf / flake
and would it be possible to bulk the refined gold up to scrap to add weight and not reduce the purity because not adding an alloy as such to lower the karat
Going to go buy some stumpout tomorrow if i can find it in the winter
For better results you can always try sodium metabisulfite. Chemistrystore.com has some.
For over the counter tips though, stumpout by bonide is listed as 99.9% in the MsDS.
Also post a picture of your melt when you are finished. Also dont forget a flux when you melt, 50 mule team borax works great.
One gram of gold is worth 53 USD.
With those chemicals and no recycling you can do upto 20his grams depending on your source mats.
Math looks sound to me.
The stuff cost massively more here...
As an example: The my-Acid 31.5% goes for 16 swiss francs a litre. One litre is 1/3.78th of a gallon. --> 1 gallon whould cost around 60 swiss francs which is around 64$. over 10x the price you have. Lucky you! :)
Bleach in this concentration is around 36$ per gallon.
Peroxide 3.3% is 9.80 swiss francs / litre --> around 40$/gallon
I have found no price for Sodium bisulfate, but lets say it is the same price you have (i doupt it).
Makes a net invest of 147.7$ for the swiss guy.
Gold is 53USD if 99.999% pure which i dont think will be the result here or at least you cannot sell it for this price.
Anyway, if i go for 50$/gram with 20 grams coming from around 150$ i get an income of 20x50$=1000$ and a bill of 150$ for materials yielding 850$ net gain.
However i now have the chemicals AND the leftovers i treated.
to be honest, i have no idea of the volume of the leftovers which now also have to be treated as chemical waste.
Also the chems have to be given back because they now have massive ammounts of heavy metals in them...
I just checked the cost for such stuff (The waste-chemicals) and it hits me with 51-87 swiss francs per litre . Since i have 3 gallons of chems (equals around 11 litres), i have to spit out around 561 sw.fr. to 957 sw.fr. --> 600-1000$
And i still have the treated electrical waste to dispose of...
Seems like if i wanted to make money this way, i whould have to:
- Find a cheaper source of the chems ( --> International supplier)
- Dont go the official ways to dispose of my chems and waste (How good whould THAT be? Bad...)
Ahwell. Was fun thinking of it and checking the costs. Not feasable for swiss guys thou. :)
I wish you all the best and a cheap stream of chems and good parts! Stay save and keep away from the fumes.
Cheers,

Memory Simm, Dimms, Sdram, and Sodims. 1.3 grams per pound.
ISA Cards - 1.3 grams P.P.
PCI, AGP,, PCI express .90 Grams P.P.
Items plated prior to 1995 can have much higher yields such as 72 - 32 pin memory. Military electrons and the likes can have 100% better yields.
I hope this answer was satisfactory.
this number is it (0.90 gr pp) or (90 gr pp) ....
thanks so much about your expiriance...
This is really cool, but the layout and your wording are a bit confusing at times. The last thing I want is to be confused when messing with acids... Otherwise, great instructable.
