The Modern Approach to Biomass Recovery Dec. Thru Oct. 1981


Just do the math [sic for 1970's x-ray film]

You can't burn it, X-Ray film for silver in the open air without
losing 40% or more of your silver and causing big problems
for polluting and it's expensive and difficult to recover silver with caustic.

Pyrolysis is an option I have helped develop
by providing the final stage to convert the hard
carbon particles that the pyrolysis machine produces
to 9999 Fine Silver.

We processed 500 pounds an hour 24/7 with this machine

From 2000 to 2004, I ran about 6000 assays, representing some 50,000,000 pounds of film scrap, for a large film refiner in Texas. Every type film under the sun was represented and it was a good cross section of what was available nationally. About 60% was developed medical x-ray film and about 30% was developed litho. Industrial x-ray and undeveloped film, both x-ray and litho, made up much of the remaining 10%.

The only medical x-ray that ran close to 0.2 tr.oz./pound (actually, about .18) was undeveloped rare earth x-ray, which was relatively rare - maybe 1% of the total. On an average, developed rare earth x-ray film only runs 0.1 tr.oz./pound. No developed medical x-ray film, since 1985 (when rare earth film was first sold), averages over 0.1 tr.oz./pound.

Seems like the trend is to Digital X-Ray imaging. The supply of X-Ray film scrap is bound to decrease over time as facilities go Digital.

Not a good business model. It'd sort of like setting up to do 486 processors. There's only so many left.

Dear Sir,

Thank you so much for bringing up this very important point in your observation.
I recall that the yield of silver in film was dropping to .17 in the 1980's
I haven't kept up on the film industry.
Much thanks to you Sir for your observations.

Very happy to meet you.

Thanks for you comments Irons...

I can't agree with you more in that about X-Ray not being a good
business model and finding 486's.
I had a neighbor that is a distributor of laptops and pc's
and he said he could get pulverized motherboards by the traincar load and has
sources for high grade chips and pins already separated.
I wanted to get something going with him and
he said that he is already processing down in Mexico.
I don't know if he was B.S.ing me or not but he gave some good food
for thought.

Dad and I got started with 1 phone call from a farmer from the Dakotas.
I said ..Can Do and he drove out to California with a 3/4 ton Chevy full of
silver coin 900.

I would like to set up for running chips and high grade computer
scrap. It's a super easy process with dilute CN.

An engineer friend of mine that I worked with at MAC in Hayward said
he had some engineer friends in Nevada that were making a killing at it
with around 6 employees.

They have the stripping tanks and precipitation or carbon pulp something
that I am not up on . I used to heat the CN and drop with zinc dust.

I am happy to meet you. :lol:

Dear Gold Silver Pro,

Thank you so much for bringing up this very important point in your observation.
I stand corrected and am very impressed and humbled by your credentials and experience.
I recall that the yield of silver in film was dropping to .17 in the 1980's
I haven't kept up on the film industry.
In the blog , Please observe the date on exhibit 2, (July 2, 1981) in the post: PYROLYSIS pg. 49 - 65 The Modern Approach to Biomass Reduction.
I have only made reference to my experiences of the industry back in the days, mid 1970's through late 1980's
It was a law that film was held by the hospitals for 7 years so we were only able to purchase film produced before the mid 1970's
and some of that was already only yielding .17 oz/lb. I am sure that with the rising silver prices that film makers are constantly finding
new ways to produce lower silver content film.
I am very glad that you mentioned that the film that is available these days, ( post 1970's) is running much lower concentrations in silver content.

Much thanks to you Sir for your observations.

Happy to meet you
