Hi, I've been making jewellery for almost 10 years and have never yet sell scrap. Too much anxiety in the process but with the metal prices where they are, I think I should do it. You can imagine, I have a lot.
At the moment, I have separately:
- Silver wire and sheet scrap, mostly clean but with some gold in it from mixed metal pieces
- Silver bench sweepings (relatively clean)
- Floor sweeping from my polishing room (very dirty)
- Higher carat gold (18+)
- Lower carat gold (14 and 9)

Is it better to send these separately and pay refining/assay fee for every type or mix them together and pay only one fee but possibly higher? Does it work that way? If I send the silver scrap, will they do full analysis and pay me for the gold in it too? For the lower carat gold, do they also pay for the silver portion or Pd in the white gold etc.?

And I have some practical questions. I have Cookson scrap pot. Can I fill it, pack it in whatever type of packaging (box etc.), print their label and send it? No limit on weight or (reasonable) package dimensions?

Thank you!
