When the reaction finally stops, add an additional very small quantity (a few mls) of nitric. If bubbling starts up again, then not all the
contaminant metals have been dissolved yet and once again, allow the process to continue on its own. If adding further nitric does NOT result in
bubbling, then all metal contaminants will have been dissolved leaving behind relatively pure gold.
At this point, you can dilute the blue liquid with water, wait for the gold to settle to the bottom, then carefully pour most of the liquid into
another container. Just be careful and don't pour away any of the gold !!
Add some more water to the settled gold to dilute even further any remaining liquid, then let the gold settle again, then carefully pour most of the
liquid into another container ... again, DON'T pour away any of the gold.
After repeating the dilute/pour procedure a few times (basically "washing" the gold), we end up with something like this:
well no Answer yet on my posts hope that the next time i log on that some 1 will give me a risp ..........
i would like to know what % is the gold in the post and picks it looks good but the % ???'
if i leave it in this state and do a large batch of this is it the same ...
like i do 10 first step and then i do all of it at once the second step????
