Is it worth stacking Xray films for silver?

Hi all,

Just wondering if anyone has any information on whether it is worthwhile stacking xray films (exposed) for their silver content, or if extraction is a viable option.

Also any ideas how much silver is in an old roll of 35mm camera film (unexposed)?

Thanks,

Au-

 

"We used to extract silver via bleaching & fixing from old B&W motion picture films.
These were print stocks, not camera films, they contained approximately 1 oz per 1000 feet of 35 mm film."

No...this is not how one silvers

 

keyboard mylars perhaps. ask miniroo.

 

I assume it would be much the same as to how the silver is within, xray film and keyboard mylars...correct me if im wrong but a much the same process in extracting i think but yest im sure miniroo can clarify for us all ?

Cheers, HAPPY STACKING

 

I know they do contain silver and that they do extract silver from them but how economical it is and how practical it is for the individual to do at home I couldn't speak to. You might have luck selling the film for others to do recovery on, I've seen them for sale on ebay that way.

 

We have plenty of rejected x-ray films that we sent for recycle. Not to my knowledge that they can be done easily to get the silver.

X-Rays vary a lot obviously but yes it's still worth stacking x-ray film for silver recovery.

The main difference in x-rays to keyboard mylars is the silver content hasn't changed in a keyboard mylar.
Whereas an x-ray's silver content has reduced because of newer technology, like every decade from the 70's.

Keyboard Mylar: 100 kg = 2.5 - 3.7 kg of recovered silver

X-Ray 1970's 100 kg = up to 10 kg of silver
X-Ray 1980's 100 kg = up to 8 kg of silver
X-Ray 1990's 100 kg = up to 6 kg of silver
X-Ray 2000's 100 kg = up to 4 kg of silver
X-Ray 2010's 100 kg = up to 2 kg of silver

I just did my lower back so in a strange way i'm excited to go get x-rays.
Was dissapointed a few months ago, I went for an ultrasound, all I got back was a paper photocopy, so there's one area that silver is almost gone, they can just view images on computers now.

Dentists take x-rays of your tooth sometimes, it's only a little x-ray but them ones are still very high grade.

I don't know much about camera film, I hear 35mm film has about 1 gram silver per metre.

 

When film was used in the printing industry most big companies used to recycle the silver... my old man used to get a couple of kilo bars as a xmas bonus
