Hi,
I have done some aluminum housings in a weak nitric in the past and the gold would come off nicely, see post
Best way to process this
I did 2 housing and the aluminum on these being attacked and appears when I scrape it there is still gold underneath it. There are also flakes of gold mixed in the stuff on the bottom of the container that came off.
The only difference between these and the others I did are that these housings had been exposed to HCl vapors. What do I do with these now? How should I recover the gold off these and the gold mixed with the sediment in the bottom of the container?
Thanks
