hi everybody I hope somebody will be able to help me I processed my gold with aqua regia .
to be exact I used 10 Pentium Pro CPUs.
which should give me 10 grams of gold at the end of the process because I read somewhere that each Pentium pro CPU as one gram of gold.
after all the process was done I drop the gold with SMB the gold was dropped and dried and I had about 3 grams can anybody tell me if I'm losing gold during my process.my process was as follows
1)I placed 10 Pentium pro cpu's in a coffee maker.
2)covered with HCl and added a little bit of water let the water and HCl warm up a little bit and then add small addition of nitric acid until exhaustion.
the reaction was fairly quick about 20 minutes until exhaustion was stopped.
3)then I transfer the solution to a beaker with ice in it and put a few drops of sulfuric acid to drop the led
Silver sulfate.
4)then l filtered solution
5)then use the urea to neutralize the nitric acid
6)then use SMB to drop the gold the final residual was about 3 grams of gold from 10 grms anticipated of gold.
please let me know if I'm doing anything wrong and why I got only 3 grams of gold from 10 Pentium pro cpu's.
thank you very much
