Most Common Method of Extraction
Cheapest method, Get Muratic Acid, and Hydrogen peroxcide, mix a 75% muratic Acid mix, to 25% hydrogen peroxcide, throw all the PCBs, and other gold materials into it, let sit for 24 hours and check on it. Better to do in a warm enviroment helps the reaction. or you can use a pyrex beaker set on a sand bed over a hot plate set to low.
This method dissolves the Nickle and copper and the Gold floats off the board.
Then you must clean and filter this solution out.
Next you need take your filters and wash them out using distiled water, and then low boil off the water. so not to evaporate micro gold.
Then you need Nitric Acid and Hydrocloric, HLC for short.
This is going to be a 75% 25% mix of Nitric to HLC, this makes Aqua Regia…this will disolve off the gold..add one or 2 drops of sulfuric acid to keep the lead in the solution. so that the gold will percipitate from solution alot more pure. you make have to refine it a few times to get 99.999 percent gold.
MEASUREMENTS ARE KEY IN THIS…if you mix to much AQ when you start to use Sodium Metabisulfate AKA STUMP OUT…then the gold will keep disoloving back into the solution. and you must also slowly add the STUMP OUT..so not to over add too much..
then wash and dry the brownish copper mud using washes of hot HLC, until there is no more GREEN tint, and then do a few washes with DISTILED WATER.
the remaining powered is PURE GOLD..melt into buttons, or bars depending on how much powder you have..
depending on the quality of your electronics, gold amounts may vary. But i find doing pins or lead to be the most profitable of it all. ten pounds of RAM will get you ruffly 2-10g of pure gold depending on quality of ram.
there are tons of methods to do all this. And sites, and forums, as well, and books.. the best one REFINING PRECIOUS METAL WASTE BY: C.M. Hoke very very expensive book
