Hi there. I'm wanting to ask a hypothetical question aboug a not so hypothetical situation..
A while back I searched the forum for answers regarding a solution I had made out of hcl and bleach to disolve my gold. It did disolve the gold of course, but apparently I carelessly left other metals in the mix as well that were also dissolved, giving me a solution that was a funky blue/green color. So I found a thread on a similar problem, where the guy was told to precipitate the gold with copper. So i did this and it worked beautifully . I of course had to start over once it was precipitated, but it was a second chance to be more careful. I ended up with a modest, yet decent yield on that run.
Fast forward to now.. I'm looking at a batch of 200g of ic chips that I soaked in hcl for a week or so to remove the legs. I've incinerated them and pulverized them. And I've noticed, after dragging the resulting powder with a magnet thourughly to remove any wierd stuff, that It appears I still have some wierd non magnetic stuff in it. So I went ahead and utilized the AP method, since that's all I knew to do, and after a week or so of that, I finally see my gold bond wires without all the junk.. So it seems. There are still a few stragglers that appear to not be gold. They're just entirely too robust and thick to be gold. So I'm wondering about the method mentioned earlier. Woukd it be feasible to go ahead and purposely disolve the gold into a dirty solution, tgen use tge copper to seperate it that way, then continue the process? I'm definitely not the smartest person here, so I can't help but assume that there's a real good reason that this isn't ideal, because by this logic, one should be able to take a heap of scrap once processed to a certain point, and then just dissolve everything, seperate the gold with copper, put the gold precipitate back into solution. By its self, then drop with smb and b done with it. Seeking guidance from someone who knows better. Thanks.
