Just a quick question:
I have started a small scale waste treatment to familiarize myself with the process before I start slogging large volumes and realize I made a mistake somewhere... I did a small batch of pins with solder in AP. After filtering off and refining the gold, I put my contaminated AP in a container with Copper to cement out any valuables. Then I decanted off the clear solution to another container and adjusted pH and added Iron/steel and got crystals of Copper, so far so good.
The problems is now that my solution is barren of Copper, my cemented Copper (and mixed in Lead/Tin/Nickel) is also full of small pieces of iron and rust... I was hoping to be able to add the cemented Copper straight back to my stock pot, but is that really advisable when I have visible Iron contamination in my Copper powder?
What can I do to clean it if adding the Iron back into my waste stream in the stock pot? Or can I just disregard the Iron-contamination as it will do the same job as the Copper?
