Nice cathode SDHillbilly

I work in Hydromet and I'd love to see more pics of your setup

 <-wave-> Here are some pics of some bars I tried to pour a couple of days ago.direct smelt of some high grade ore  About 42 lbs.no assay yet but nice gold color. Not the best but I can melt again  <-dont~know->. Ipsumo, it's not much of a system yet  :( 5 gallon buckets  but i just learned the graphite plates do dissolve in my solution when i electrowinn.  Hard to melt  ^#!  So now I must use different material for anode  <-thinking->.
just keep digging

You're dissolving your graphite?!? Geez, never saw that one coming! What other anode materials have you tried?

 <-wave-> Yes, I was told graphite would not, but no biggy. I'm just still experimenting. Pretty positive now  that I'm going to leach sx/ew lower grade and direct smelt high grade oxides. sulfide ore just grind to float I tried some different steels and just cathodes that I make from direct smelting, but it would be nice to have anodes that don't dissolve.  Still copper cement is so easy to make and plenty of buyers.  Cheaper setup too. Ipsumo. I'll grab some pics of parts I have, but here's a good history read on sx/ew 2002 anyway-   https://www.saimm.co.za/Journal/v102n08p445.pdf

Try using a passivated titanium cathode in your parting cell.

 <-wave-> Thanks tinman_II. Sorry I just realized that I meant the graphite anode is dissolving not cathode  <-d'oh->. but this site has anodes that they say wont dissolve.  Stainless steel or platinum plated anodes  www.belmontmetals.com/product/anodes-electroplating/   Stainless steel sounds way cheaper.

Thanks for the experiment, flatten out the copper then give it a quick scrub with either sandpaper or steel wool, if the Ph is 7.1 as you earlier stated add a few drops of Hydrochloric or sulphuric acid. Just a few drops of acid should do the trick.

Once you have confirmed precious metals then it's time to speak with a Dow mining representative to see which resin is suitable.

Dow manufactures resins for all types of Ph, including direct recovery from active cyanide leaches which would be way above Ph 7.1

Good luck with the experiment, hopefully your copper will show some blacks collecting on the surface area.
