Hi all,
Due to a lot of health issues (inguinal hernia, with damaged nerves, broken foot in 9 places, etc) I am way way behind all my information, and projects with my gold recovery.
Last couple of days I'm trying to clean and sort all the mess out, because I have way too much buckets, and jars filled without knowing what it is.
I was checking out my stockpot, and noticed all the copper had a solid white plating / cement on it. Put a piece in fresh HCL and it cleaned right up. But there is a bunch of copper in about 20 L of stockpot residue, and it is all white / grey..
Can you guys explain what is is, and how to fix it, besided cleaning the copper in fresh HCL?
I suspect it is either tin metal, of perhaps even silver because I have added AR that failed to drop the gold, so there are different metals in the stockpot, perhaps even Pd.
I'm afraid that if I clean all the copper with HCL and put it back in the stockpot, the reaction repeates it self, and the copper turns white / grey again. Any suggestions any one ?
Thanks, Gilbert
