Hi everyone,
First post in the forum so go easy on me
I have been reading a lot of tutorials and watching some videos(actually it was "goldnscrap" that brought me here, thanks!) and I see that the most typical process is to first separate all the gold plated either by hand or by chemical process, then use aqua regia, then precipitate with smb and optional to do some more purifications to increase the purity level.
The part that gets me confused is why is there a need to separate the most gold possible before the usage of aqua regia since there is always the possibility of increasing the purity after using SMB.
So my plan that I hope you guys can tell me if I am thinking correctly or what am I missing and why shouldn't I take this approach is the following:
I have tons of old cellphone boards/ram/all types of gold containing electronics on them(already removed all the plastic)
And I was planning on grinding the entire thing into the finest powder I could and then use aqua regia(still waiting for the nitric to react so I don't have excess) directly followed by the precipitation using SMB, I know that this would give me a low purity level, but after that I would repeat the process a couple of times and I would expect a high purity level.
That's the first option, the second option would be to take a similar process to the one used to process chips.
First melt them with the furnace(everything in it, boards ram etc) and then aqua regia followed by smb and a couple of purifications.
Does this sound logical? I have a pretty big batch and I really don't want to ruin everything, also I am only interested in the gold for now.
Thanks in advance for the tips.
