Ok after a few failures gold is stripped and there somewhere but after the SMB I have nothing.
Before I try again or just give up I am trying to clean up my act.
So even though I have tried to be careful I with power current and voltage.
I am still ending up with copper solids in the sludge at the bottom of my cell.
I think I am just taking it too far or that the sulphuric is now polluted and other stuff is going on.
From what I have read I believe that if I reverse the polarity with a lead anode and copper cathode
(I think I have that the right way around) that will electroplate the copper out of solution.
Also the next lot of sludge that looks like it has copper in it. Last time there was a lot of lighter sludge with it I am guessing that is copper.
I am thinking that I can dilute the sludge then add nitric to remove the copper from the sludge leaving mostly gold sludge.
-Filter out the solids.
-add HCL to the liquid. then if there is any reaction add SMB to drop any gold. (I will make an SO2 bubbler later to do that in a cleaner way)
-do the AR on the remaining sludge and filters when there is a reasonable amount.
Is this the correct way to sort this all out?
Clearly I am getting a little muddled at the moment.
I have been reading a lot but it is all a bit of a jumble in my head at the moment.
