Final Part. For gold recovery, make aqua regia for gold dissolving. Use 1:3 ratio of nitric acid and hydrochloric acid to make aqua regia. Aqua regia should be half an inch above from processors. Leave it for two hours for complete gold dissolving in aqua regia. After complete gold dissolving adds some drops of sulfuric acid to the solution.

At present, majority of gold has been recovered from gold and silver ores by means of cyanide process developed at the beginning of twentieth century as schematically shown in Figure 14. In this process, pulverized ores are leached using alkaline cyanide solution to extract gold as gold (I)-cyanide complexes according to the following reaction:
Filtering. The next step is to filter. Silver is in the solution as silver nitrate (AgNO 3 ), whereas the gold and a few other metals that weren't attacked by the nitric acid, plus the impurities ...

Gold recovery process from Ceramic CPU's Part 1. Abstract of the Gold and Silver recovery process: Size reduction and lids removal. Dissolving the metals with Aqua Regia.
Gold refining yields of the Pentium Pro have been reported to be as high as around .33 grams per CPU. Note: The larger package size of the Pentium Pro CPU also means there is more ceramic material per pound, which is why the Intel 386 and 486 CPU's command a higher recyclable value than the Pentium Pro.
There are several ways to recover your gold from the leachate, some of them expensive and dangerous, but with a little preparation, zinc will work. Dilute the leach solution with 2 times the amount of tap water, and check the pH. It should be between 1.5 and 2. If not, use a 10% sodium hydroxide (lye) solution to raise the pH to about 2.
Jan 6, 2012. #12. Jojo, some one onces said: "there's more than one way to skin a cat"! Well, there's also more than one way to recover &/or refine your gold. Mercury is one of the most hazardous of them all. The old prospectors used the mercury to "capture" the fine gold, then they had to heat it. This produces very toxic fumes that WILL kill you.
We (1) Removed the lid and chip with heat and a vacuum probe and removed the bonding wires; (2) Chemically stripped (electrolytically) the gold plate and gold alloy brazes selectively without attacking the base metals (the crux of my invention).
If you still can't find a library, there are a couple possible reasons: The library doesn't have this title in their digital collection. The library doesn't offer digital titles through OverDrive. Find in other nearby digital libraries. A very easy process to Recovering Scrap Gold from Fiber CPUs

Step 1: Extracting Gold From Scraps Collect any gold-containing metal scraps to which you have access, including jewelry, computer processors, old telephone wiring or gold tooth crowns. Keep in mind that outdated electronics are likelier to produce parts with a high enough level of gold to make the procedure worthwhile.
SCRAP CPU. GOLD RECOVERY FROM CERAMIC PROCESSORS(Scrap CPU) Gold recovery from scrap CPU ceramic processors is very easy and profitable business.
Aqua Regia Process Generally aqua regia process is used to recover gold from computer CPUs. The reason of not using cyanide process on CPUs is that CPUs have very thick plating and gold wires in it, and that's why cyanide process takes too much time to remove gold from CPUs.
