Okay here it is.....
Almost 1year ago I bought 200lbs of green industrial X-Ray film. I began by buying
Some sodium thiosulfate (fixer without a hardener) I would sit for hours next to a 5 gallon bucket with 2:1 fixer and water. I later upgraded to 3 buckets. I would put in 1 piece at a time in each bucket, as it cleared I would add more film. Once the film got to about 6 inches think I would fish the blue plastic film out and move it to a rinse water bucket.
Once the fixer was saturated (took 5 minutes to clear the film) I added 1/2 gallon of HCl to convert it to silver chloride. Once it all settled I drained off the acid and transferred the AGCl to some 1 gallon glass jars. I then added more HCl and some iron nails.
Once it was all converted I siphoned off the acid, poured the grey concrete colored silver into a bucket again. Now I would take 3 boiling pots of water and pour onto the top, and stir thoroughly. Once it settled I would siphon off the water and repeat with more boiling water rinses. It would take about 4 or 5 times but it would get to where it settled quickly. Now I would siphon off the water and then I would add 1 gallon of HCl to eat up any remaining iron. I would let it sit 2 or 3 day stirring often. Then I would siphon off the acid and repeat the boiling water rinses until it settled quickly.
Then I would dry it.
So out of 200lbs of green industrial X-Ray film the yield for me was 204 troy oz.
Thanks for reading
