Hello everyone, I have been experimenting with the Wohlwill process in many different ways. I have seen others example of making Gold Chloride and the method building and operating the cell. My problem with it is i get a high amount of Si ( Selenium ) in the final product. Maybe trace amounts of something else but I'm trying to figure out where its coming from. I have refined mostly jewelry to up to 99.75% +/- with and average of 0.085 Si and other impurity.
When making Gold Chloride, the gold to be dissolved for it does it have to be 99.99%? Can it be made from 99.25%?
Can Selenium and other contaminants be introduced when using cheap HCI and SMB? A lot of it?
Do i have to use a 99.99% as a cathode? can i use cathodes made from Titanium or Stainless Steel?
I have felt filter that I'm planing to use. I also read into ceramic filters as other possible add on. I'm sure of all the purity readings from my portable XRF Analyzer.
Id like to know if there are any better ways to prepare the solution, look out for what I'm using and or refine this processes i just described better?
