@ Yeah you can buy the cation resin separately. Batch or column is the question. I need to learn more if iron fouls it. It might just not be worth the trouble for small scale operations. You can ash it also but seems kinda like going in circles if it is full of iron.
I want to try cation resin separation. You can get industrial cation resins cheap. If I could selectively drop the copper and iron that would be cool.
Just like water filters

I wonder if the iron can be back washed out , with water softening salts ?
@ That’s kinda my next question. I need to run some trials. Maybe over the holidays. Need to try different cations like Na+
@ My hope was to put the ecogoldex into the resin and selectively elute with either salts or acids. This would be in a column.
By the time you put it in acid. You need 50 of them to make any significant gold !
Maybe a better process like pulverizing then smelting would have a better result but to me every little bit counts .
@Hill-13 I'm not sure. Seems like a lot more work. But your right every little bit counts
And you get lots of iron and copper in your product to deal with. At least with leeching.
To be accurate I should have counted the other metals sounds like a good idea
