You should be working with more than 3 of those processors so you can actually see the gold.

Jim,
I haven't started the whole CPU lot yet, this was left over from previous lots, and I was trying to practice recovery method I mentioned, nitric leach then AR leach for gold. Still i should see some sort of brown gold powder at the bottom, shouldn't i? I saw plenty of gold pins ( foils ) what happened to them?!
Regards,
Kevin

I do not know. I just know that working with very small amounts is tough to do. I think those processors have been determined to have about 25 cents worth of gold in each. So 75 cents of gold would be difficult to see when recovered. Maybe others who have run small sample tests can give you some advice. But I would run enough to actually see results, and with those processors I don't think 3 is enough.
Your stannous results are positive, but week. Stannous is very sensitive, and detects very small amounts of gold. That does not mean it is an easily recoverable amount.
