I usually get a 3%-5% yield off gold filled material. The bowl is a 1 liter dish so it's quite a bit of powder. This batch yielded 68 grams.

I get the material from garage sales, estate sales, etc. It's sold as gold plated junk jewelry, usually. I buy bags of it for pennies and seperate the gold filled from the plated.

If gold prices go back up, I'll make a stripping cell for all of the gold plated junk I have.

Wow! I only yield about 2.1%-2.4%. How do you get up to 5%?? Is this accurate? Your 2.5 kilo batch seems to have yielded 2.7%. Would love some tips.

Also, did you process the 2.5 kilo batch all at once? If so, what size beakers did you use and what’s a brief rundown on your process for managing so much at once? Thanks so much.
