Hi everybody. I have a green palladium solution. I took a sample of it and I added a DMG and sodium hydroxide solution to the green pd solution. It precipitated green powder. I read in some forums that I should filtrate the powder and wash it with cold water until it gets yellow pdDMG powder. When I washed it it got white color. Am I doing something wronge? Or I didnt make the DMG solution correctly. I tested the green solution with Stannous chloride before and after adding DMG solution. Before it was positive after adding it got negative with the green precipitate. What should I do?
Has anyone been offered a questionable ( Gold ) metal for refining ? I have been approached by an acquaintance to extract gold from a yellow alloy , supposed to be Dore' bars from E- Waste . I was shown a video of this metal being melted prior to casting into popcorn . I was amazed at the fumes and glow emitting from the crucible it reminded me of News Paper pictures of Iran pouring molten Uranium . Could the metal I have been offered be depleted Uranium? I have no Idea where to find out, also I have not taken possession of any of this material.
