Ok I got the brown in the bottom the gold on a hot plate and let it set for a while and come back and it is gone, so I test it their is gold it is telling me so now what repecipitant it or what I'm lost ?
Ok I thought it was all percipitant it did not bubble or fizz on more before I added the storm. Now I'll go back in and look at it. Now their are clear crystals in the bottom of it. Should I turned the hot plate back no to redissolve it?lazersteve said:Sounds like you tried to percipitate before you removed all the nitric.
Did you use Urea to remove left over nitric?
Did you already add SMB? (percipitant)
Your gold is not gone, the nitric which was not removed just worked with the remaining HCl to redissolve the gold.
The second time around you need to make sure you remove the excess nitric before adding any SMB. You can remove the excess nitric by adding urea until it no longer producess bubbles (fizzes), or by boiling down the AR, add more HCl and boil down again, repeat unitl no more brown fumes come off.
After you are sure the nitric is all gone you can add the SMB.

no just turned the hot plate onlazersteve said:Did you add urea yet or boil off the excess nitric?
Ok I will do that and get back with you thanks Chrislazersteve said:You need to remove the excess nitric before adding the SMB.
Ok first I had a oz of pc fingers. Using 1 qt. of HCl and a quarter of a pound of subzero. I let this go overnight on a hot plate. All the gold was gone in the subzero then I put urea in it. To me it looked like it was done, no fizz or bubble. Then I put in the storm percipitant. I saw the brown in the bottom so I let sit. Well I fell asleep, woke up in the morning it was about 3 or 4 hours later when I went back. The mud was gone but I had clear crystals in the bottom of the jar. Now this is were I started tonight from talking with you all. I tested it and gold is in it. Now I'm putting urea in until no more bubbles even little ones. Then I will put in the storm next, is that about right ?lazersteve said:Chris,
Could you briefly explain what you did to get to this point? Be sure to explain each step in order. Include the following information:
1) How much scrap did you start with?
2) What kind of scrap?
3) What chemicals did you mix?
4) How much of each chemical?
5)What happened next?
6) Did you add anything else?
