Hi,i am new on this forum and in recycling gold with acids... i bought some ,,intel pentium pro ,,cpu's to try to extract the gold from them in AGUA REGIA . BUT HERE IS WHAT HAPPENED...
First with propane torch i take of the back side lids than i put the 3 CPU chips --Intel-Pentium Pro-- into Pirex Glass cup.
After i mesure 30gr Sodium Nitrate and 60ml boiled water and mix together.
Then i add it to the Pirex cup with the Cpu's and then add about 150ml MURIATIC ACID.
After a few hours all the gold is disolved in the AR....
After i filter and wash the rest of the chips with hot water,than i add a little bit urea and after that i add Sodium Metabisulfite.
i leave it 24hors .
But the gold powder that i got on the end is about LESS THAN 1gr FROM 3 CHIPS ..........WHICH IS THREE TIMES LESS
PLEASE LET ME KNOW WHAT DO YOU THINK...AM I NOT DOING IT RIGHT OR THERE IS NO 1GR OF GOLD IN EACH CPU
