Video discussion. Gold recovery from 14kg of CPU by using the lead bath method.

SS cage works as long as its not fine mesh. Too fine of a mesh and the "pores" gets clogged by the solidified litharge.

This is the latest lead bath I did:

Great feed back and great video showing some mistakes and learning points! Those are the best imo letting people learn from your mistakes.

@Owltech ;
How do you experience the lead fumes, if any? Are there a lot fumes or is it a negligible? Do you wear a mask?
Do you reduce the lead oxide back into metal after cupelling?

I just saw you wear a mask in the video. So something to keep in mind when I start experimenting.
I was wondering if the button with silver and gold can be put in the silver cell after cupelling.

Lead fumes are a nasty thing, use common sence and a mask rated for welding fumes, change your clothes before and after work, wash yourself after work with plenty of soap, position yourself so the wind is at your back, don't exceed the needed temperature. A mobile weldig fume extractor should be more than enough to deal with the fumes from small batches like mine. I never experienced any health problems, but it's never too late. I drink 2 liters of milk every day, but thats because I'm loving it, some old folks say it helps for heavy metal poisoning.

Yes, reduction of litharge to lead easily done with a source of carbon
