Hello to every one on GRF! I a newbie at refining and I have made numerous rookie mistakes and wasted lost of money and gold. I decided to start reading up on refining and looking it I forums and you guys have answered a lot of questions. I am not a guy that just wants to do this as a hobby. I really enjoy doing it. I have a buddy that owns an industrial radiography and inspection company and he decided he would give me all his fixer solution and waste film. I think I have read somewhere on this forum that you can use zinc to precipitate the silver from the solution. But is there an easier cheaper way. I know zing isn't that expensive I am just curious. I will be getting about 100 gallons every few weeks. I also have tried to get the silver from the film and I am having trouble. I cleared the film with bleach then filtered of the greyish substance after it settled. Then I dried the grey and put it in a crucible. I then api called borax on it and heated it to a honey like state. I let it cool them I tried to dissolve it in nitric. It did not dissolve. Can anyone help me with both of these processes? I love doing this but I want to make sure I do it right. I would really appreciate anyone's help and I hope you all have an amazing day. Thanks for your time.
