Tip to cut the time removing silver from x-rays. The silver is only on the dull side. Put two sheets together back to back exposing both dull sides while dipping. I've been a photographer for 40 years.
For higher yield buy photographically unprocessed film , Silver halogen that is on the gelatin of the film was already used to create silver oxide ( the dark image on the film) hence creating negative image, Most of silver halogen (silver bromide ) was already regenerated to silver and stripped in fixer bath . Recovered silver remained in the hypo and you bought material that had less than 20 % of original silver content. I checked on Ebay for unprocessed Xray film and for the price you paid you could buy unexposed film and recover 5 times the amount of silver you received, You were correct to assume 2.5 oz of silver from 5,5 lb of film, but because most of the weight was in cellulose and silver had already been extracted before you bought it 1/2 oz is a good yield . I have been working for a large photo company for 20 years and silver recovery was part of my job. Recovery was done by methods other than bleach stripping, and hypo solution would yield 1 oz of purest silver per 1000 sq. ft of combined photographic paper and film processed.
Hello. The conventional film are using developer to develop the image. Now the medical industry mainly use computered radiography which we call it CR film in Malaysia. Is it contain silver too? I have some sample photo of it. Thank you. Khoohmkhoo956@gmail.com Here's my mail. Thank you.
We used to recover silver from the fixing bath of black and white film development. We used powdered zinc to precipitate the silver out of the solution. Allowing the zinc silver mix to settle out we would recycle the fixing bath and allow the mud to dry. This mud can be smelted to separate the zinc from the silver.
Smelting is a term used to describe extracting metal from ore. To seperate the zinc and silver, both are dissolved in hot dilute nitric acid. Then copper metal is introduced into the acidic zinc/silver solution. Zinc, being above copper in the reactivity series of metals, will stay in solution. Silver being located below copper in the reactivity series of metals, will cement (precipitate) out as nearly pure silver metal as a grey powder that looks like wet cement. This is where the term "cement" comes from. (Edited once for spelling).
Great video, thanks. Can I add to the calls for a video on the reclamation of silver in suspension please ! Years ago, when film development was manual, we use to sell the spent Fix solution for the modern equivalent of 20 Dollars/Gallon (with a lot of wheeling and dealing between us and the scrapman) I was told by old heads that the process involved a trickle charge of current and produced 'Black Silver' - I've still got some 'Silver Estimating' papers somewhere... i was also told that silver recovery from film was done by burning the excess away to leave silver behind - I've no idea if this was true, its just what I was told !
Fill a bucket full of steel wool and pour the fixer in stirring ever so often and then letting the silver bind to the steel wool....once all the fixer is gone and drained out rinse the steel wool with water and walla....there's your silver. I have over 5,000 pounds of film in my shop so I believe bringing it straight to the refinery works best for me. BTW.....the steel wool has some sort of chemical electrical reaction to the fixer and silver so the silver binds to the steel wool.
If I did this again I'd use a 5 gallon bucket instead of the small bucket that I used in the video. If I remember it took me 6 hours to strip five pounds! Good luck with it.
My brother I just died in April 2022, he was a chiropractor. He has years worth of x-rays I’m presuming 500 pound anyways, my sister-in-law is giving that to me. Just for this purpose… Thank you so much for the info!
Excellent video. I wonder what one would get as yield from soldered copper pipe ends, since that type of solder contains silver. Not to mention solder that is sucked off of old print circuits. I gather quite a bit of it working on electronics, especially vintage electronics where parts are soldered to contact bridges. Thanks for your sharing your knowledge and video. It was entertaining and interesting
I bought some silver solder from the welding supply store. I've had it for about two years now. A whole tube of it for about $50 bucks. I had forgotten all about it. It would make a great video. Thank you.
13:37 here you see a man MOVE'N with a purpose,,,,,,,,LOL ka-ching,,,,ka-ching.,,,,,Mrs Sreetips is smile'n.It's look'n alot like Christmas,that happy time of year.
It is a bit tedious but it is a simple process. Break the silver oxide batteries open and use nitric acid. This could be used as the electrolyte for your silver cell.
Well in case you will repeat this recycling I suggest 2 faster methods like: - Cut the plastic: A paper shradder would be GREAT cheap and effective. A paper cutter as you used for cutting the electronics fingers from those 150++ boards that you got more gold than you expected - Bath the plastic: I suggest using something short and larger so that you can put the plastic all inside without the need of tipping in-out something like OLD PHOTO DEVELOPING but bigger. From what I can spot in the video, the silver would go away from the plastic very nice using a brush. - Settling of the metals: I think that some kind of "VIBRATION" would make the settling A LOT FASTER! I would be nice to make a desk with a drill that is gently beating the undersurface of the desk, in this way all desk would slightly vibrate to facilitate the settling. Hope that would be a nice addendum to your future X-ray silver recovery method ;)
When using an x-ray automated x-ray film processor a silver recovery unit is attached in series to and to the fixer tank drain line. The silver recovery may be an electrical type which traps the silver magnetically to the recovery unit or is simply a 5 or 10 gallon bucket with lid stuffed with steel wool which attracts the silver to the steel wool. Each month the processor needs maintenance for cleaning and fresh chemistry to develop the x-rays and when the fixer tank is drained from the automated film processor the fixer flows through the recovery unit before going down the drain. (also all overflow fixer from everyday processor use goes through the silver recovery unit). Depending on your film volume the recovery units are cleaned or taken outright and refined in a similar manner as this video.
So far Im at 20:32. I really like how those x-ray films can be harvested so easily for their silver! ... An idea came to mind that, perhaps, the water and bleach could be distilled such that you have just the bleach separated with more of your silver compound left mostly alone; not sure if that would work, but perhaps if someone had a lot of x-ray film to process it might make the process easier. ... As well as possibly taping the film lengthwise, placing a roller into the bleach and water, and setting a motor to turn the film through the two sections at just enough speed to allow for the silver to be harvested automatically without the need for assembly-lining it... Gosh, am I lazy.
Hi. Thanks for the video. I have actually done the silver chloride/lye/ sugar methods a number of times. I like it. The largest batch I did was 40#'s Xrays from which I got about 2 ozt of silver. I used lye to strip the Xrays, It appears your bleach did it much quicker, so I may try that in the future. When it came to the sugar, Kyro syrup alone or with a little honey and water works great. Much quicker. If you put too much sugar in you'll have brown waste which is the sugar being carmalized. It has caused me not problems. If I can find the picture of the bar I got I'll post it. The yield you got appears consistent. I didn't expect you to get the couple ounces you mentioned in the beginning of the video with the amount of Xray film you had. It of course varies with the quality of the Xrays. Older Xrays (which mine were) have a denser coating on them compared to today's, that is if you can find Xray today with all the places going to digital. Thanks again for the video!
Great demonstration, I've always wondered how silver recovery from film works. That 0.525oz is a much lower yield than I expected from over 5lbs of material, which is OK, because now I have a realistic idea of what to pay for this type of silver recovery scrap. Thank you so much for taking the time to explore all of these different recovery and refining methods, and sharing your findings with all of us! Do you have a Patreon or some account where I can make a monetary donation to help keep these videos coming?
It seems a fish tank would be ideal for this process. you could put the entire stack of x-rays into the tank with bleach in it, and then pull them out 1 at a time to rinse them off.
This is a great video..many thanks, having worked in the medical X Ray industry for years, I have a good stock of X Ray film silver halide recovered from electrolysis units, I would say it is around 5kg....however it is like a fine black sand with a sulphur like odour, it is very dense and settles quickly in distilled water, IE it forms a sand like layer, but it is black and not grey like your metallic residue detailed here...do you have any suggestions how to process it to metallic silver ( it is definitely silver as it has come from recovery machines) thanks
In my experience, it may be silver oxide. Silver oxide is black in color, in my experience. If it were me, I would get a small sample, say about 100ml volume, and I'd put it in a crucible and heat it to 1000 degrees C or 1948 degrees F. Silver oxide, when heated, releases the oxygen and leaves behind pure metallic silver metal. Another experiment that I would try is to add a gram of sodium hydroxide to a 100ml sample of the black material, then stir and add some sugar. If it's silver oxide then I would expect to see the black silver oxide turn to pure elemental grey silver powder. This is what I would do, if it were me.
I love the ability to use borax as flux. Just throw the filter in there, let it burn, melt the silver, throw borax on it, melt it, and then either get the flux off separately (depending on the metal, it seems) or use some chemicals which leech the flux but not your target metal. ... One thing I saw that bigstackD did was use the current going-rate for whatever material he has harvested and give an estimate, at the time of the video, for what the harvest would yield if sold. Would be great for both seeing the rate of inflation as well as give an appreciation to the viewer (me) what these nuggets are worth. ... Then again, the weight tells all! No need to add anything to your style, just thought I'd throw it out there in case you find it interesting to try. :)
I had a friend years ago who made his living recovering silver from photo processing, he recycled x-ray films by simply putting them into the bleach-fix solution from print processing and letting the blix remove the silver into solution. All the silver was recovered by electrolysis. OK in those days he could collect 5000litres per week. Ebay is a spectacularly poor place to buy scrap for recycling. If your nearby hospitals still use film for x-rays, contact them for a recovery contract including a data destruction requirement. However the digital age has decimated photo labs with wet chemistry, and hospital x-rays are moving towards an all electronic format so there is almost no film involved and this is approaching zero over the next few years.
The reasons you gave are exactly why I bought it on eBay. The film is hard to come by these days and I needed it to make the video. I normally do not process X-ray films for silver. The silver is easy to find in much higher yielding scrap jewelry from yardsales.
Refining my own bullion and a retired paramedic. I would have never thought about x-ray film. I have no plans to either but it was a great and educational video. Thank you
Hello sreetips my name is Yoem Diaz and I tell you that I have learned a lot from you, I saw some of your videos that I would like to know how many grams of silver came out on that occasion with only 150 grams. here is the link of you tube Silver Cell Build Step by Step From Scratch thank you very much for what he does
Shredding will be a wasted effort, because the coating on the sheet contains silver. That needs to be submerged to dissolve it in bleach or Nitric acid...
Careful with the Sodium Hydroxide, do not add it to hot water. *If its the same as the industrial flake in 50lb sacks. when I was training in the building trades, we would pour the soda flake down the main and flush with the hottest tap water we could. It would react very violently, sometimes erupting if over dosed with flake. Same stuff?
I think you did great I will look for a lot of videos and couldn’t find a lot to explain specially when somebody’s talking you through it makes it better it was maybe one or two other videos that was silent great job
I worked in the printing industry (four color pressman) for sixteen years years (1989-2005), and we always operated a darkroom to make film negatives for plate making. A company would come by once a month and collect the discarded film negatives and used developer solutions to recover the silver from. They collected these same materials from printing companies all over the Phoenix metro area, and they got them for free! I imagine that a tidy profit could have been made, since they are getting the silver bearing materials for free. A streamlined operation could be set up, and you could be in the black fairly quickly (I assume). It looks like quite a lot of film negatives and used developer is needed to produce an ounce of pure silver, but once again, if you're getting the materials for free, the bleach, sodium hydroxide, and sugar are very inexpensive. The most significant amount of overhead will be for labor. Unless you are doing this for yourself, you will need to pay someone to work your operation. You'd have to keep them busy, and process enough material to cover your expenses for chemicals and wages. I imagine that they were making money at it, since they were in business for the entire time that I was in the printing industry.
some other person tried bu using hno3 likeSilver recovery by chemical leaching depends on the heating of the film in the solution of oxalic acid (H2C2O4), nitric acid (HNO3), sodium hydroxide (NaOH), at boiling temperature for the separation of the inorganic component from the polymer layer. The development of X-ray film leads to waste from the fixer and from the aqueous solutions containing from 1000 to 10,000 mg Ag/L and respectively 50-200 mg Ag/L silver in form of thiosulfate complex how do u seen ?
Tem, you're way over my head here. I got this to work because I'm familiar with these reactions from my years of refining experience. I used bleach to get the silver off the films. I duducted that there was silver chloride in the material that came off the films. So I added NaOH to convert any silver chloride to silver oxide. Then I added sugar, just like we use to sweeten our breakfast cereal, to convent the silver oxide to pure elemental silver metal. Rinsed off all the sugar and lye, then melted the silver into a button. I bought those films for $100 on eBay because they were guaranteed to have silver on them. I needed them to make the video. Some films do not have silver. I don't know how to tell which do and which don't have silver. All I really needed to know is what solution was used to get the silver off the films. Turns out it's just regular household bleach. The rest is history as documented in my video. Good luck!
Did a demolition in an old doctor's office and took to the shop over 1k lbs of xrays, a summer project and your video is the best put there. Common chemicals while others weRe asking for money for the chemical list, you shared this with us for free, thank you very much, great video.
Well, it's 3 full pallets, now that I moved them again it's more like 2k pounds. Willing to donate one full pallet to you and the channel, if you do a video showing what a 3 lbs plus of silver looks like, but it would take awhile, but worth it maybe for the channel and the cash. It would be cool to get a high school chemistry class to help you or something. Just thought I would offer, love your channel and I've learned a lot, the offer is there if you decide on it, but I'm in Detroit. Best wishes, and keep rockin.
Dave, thank you for the kind offer. Are you certain that the films are silver? Some processes use film that has no silver. I'll bet that a pallet of film weighs a ton.
I learned a lot from this. Mainly, not to buy films from eBay. But I wish I kept the stack of old panoramic dental films I saw a few years ago get tossed. Maybe I can find a free stack again and refine them.
Good evening congratulations on your video, I will start the procedure you did I have enough quantities, and what I would like to ask you is if you counted the x-rays in kilos
I think it’s time for an x-ray silver recovery RE-DO! That yield seems a little low considering the way your lye and sugar reactions turned out. Seemed very incomplete. In feeling you probably got a 60% yield.
I started performing silver recovery with bleach but seems bleach made in egypt is bad quality,it couldn't strip the silver so I am doing it with hydrogen peroxide , is it ok with hydrogen peroxide ? I am surprised why bleach is not working out with me !
Really like the video but can you explain what the purpose for the Sodium Hydroxide and table sugar? There are other videos show placing the silver sludge in a coffee filter and going straight for the melt. Much thanks
I was thinking that the sludge was a chloride since it came off with chlorine bleach. I used lye to convert the silver chloride to silver oxide - but I do not know if this was even necessary, it didn’t react like I expected, but this whole thing was a big experiment. After converting silver chloride to silver oxide (I think) then I added sugar to convert the silver oxide to pure silver metal. That seemed to work fine. But I may have had silver oxide before adding the lye - I don’t know. Silver oxide will melt into pure silver metal without the lye and sugar. I only did this once. I’ll probably never do it again. It was messy, time consuming, produced much waste that had to be treated before disposal and the yield was low. I couldn’t find a video on it. The videos that existed back then showed bits and pieces, then directed you to a web site and for a fee you could get the rest of the process. This disturbed me so I decided to do a video of the complete process.
@@sreetips I think you gave all of us what we needed and proved your point. The process was interesting and easy to follow and the result was spot on. Thank you...
is naoh function and bleach is the same? lastly during melting process i saw u add some chemical what is that? i guess that is to keep the quality of the silver,yeah.I want swift response dear steeps because am working now.
If you have to buy silver scrape you are going to lose. But if you just happen to dive into a dumpster with two tons of xray film. Maybe you can break even Volume. If you ain't got volume you ain't got a thing . I got 35 lbs of silver scrape but no reoccurring source . Worth about 200 bucks from a refiner . Maybe I can find a suckered on ebay. Ebay seems the way to go . I have dealt with refiners and you can throw 3ed party assays out the window . The refiners are only going to give you 20 percent of what you think you have. I'm not implying that the refiner is cheating the customer but the customer is looking on the bright side which is 80 % off
When I use this process for developed black and white film ( which is what X-ray film is) I always use a vacuum filter before converting AgCl to AgO. There is always a gross amount of the emulsion and silverhalide carried over with this process. Your yield was better than expected. Better than the same mass of keyboard mylars.
I got silver substance I believe is from a photographic product this stuff is non metallic plates . ( acetylene acetylene flame. Will not melt this silver materal.) That came. out of a electrolysis container made of wood the other plates were corroded aluminum. Anybody guess what this non metalicsilver is . They are like 4 by 5 inch plates 9 by 12 cm. One half inch thick . When shattered the interior glandular structure is solid black . The exterior is staind with dribbling copper green what could it be other than silver oxide
have about 700 lbs of plastic film with silver on it after watching this video i think it will stay where it is seems like to much trouble for what is recovered a great project if you have the time keep up the great videos thanks again
Is there any silver left in developed color photos from the late 70's, 80's to 2000 ?(common photos processed from a Wal-mart or equivalent)? Thank you.
hey sreetips, thanks for all of the content. I think that you understand what people want to watch than most other RU-vid content creators. (no disrespect to other RU-vidrs). although I think that you do yourself a massive disservice by seeing yourself as no more than an enthusiastic hobbiest, I think I have learned more about chemistry from a few of your videos than I did at school! I was wondering what is the best deal/result that Mrs Streetips has acquired? by that I mean has their ever been a time that she paid a few dollars for something that turned out to be quite valuable?
I thought Drano was sodium hydroxide with bits of aluminum added. At least that is what it was back during my time in high school. Is it different now?
This was really good! Now if we can find a supply of free x-rays and photo film I think we would be set don't you?! Thank you for sharing this it was great!
Don’t know. I only did this once. There were no videos on this. One channel had bits and pieces then referred the viewer to a web site for a fee for the rest of the process.
Followed the process. My final solution after sodium hydroxide is very chocolate colored and after sugar the product in the bottom is very gummy. Have I done something wrong? ?????
Pete, I'm not an expert on this. It was my first time doing it. When I added sodium hydroxide, the color immediately turned dark but then turned a caramel color as I added more NaOH. I think that the reaction was complete as soon as it turned dark. I should have stopped adding sodium hydroxide at that point. Lack of experience cause me to add more sodium hydroxide than I needed. Did you add the sugar?
if you know the step tell me the way having after the waste developer and fixer?how we filter them and then?now just add the chemicals? tell me in short now i have the fixer and develope
I did this experiment one time so I could make a video of the process. It was time consuming, messy, and the yield was low. I’ve never worked with waste developer and fixer. I don’t even know if these contain silver. Sorry, probably not what you wanted to hear.

I did not use any nitric acid. But I did rely heavily on my eight years of refining experience to pull this off. If this is your first attempt at refining precious metals, then recovering silver from X-ray films is not a good place to start. Was there silver on your films? Some films do not have any silver on them. I bought the films I used on eBay and they were guaranteed to have the silver.
This process can cost you recovery. Try this for you next silver chloride process. Dry the silver chloride, put the silver chloride in a crucible with sodium carbonate and carbon powder. Then heat to melting. You can also use heat to drive the chlorine out, fume hood is a must. Your yield seems a bit off, probably retained in the liquid you filtered off. If you only used distilled water you could do a rough cut estimate on the silver chloride remaining in suspension. Try hanging iron or copper into this liquid.
Don't like dry silver chloride. To much smoke. JMHO If you keep it wet, let settle well until clear, decant like he does, then use your lye until ALL BLACK, then do your sugar until brown (excess carmalized sugar) rinse, let settle well, rinse again, let settle well, repeat until clear, then melt the powdered metallic silver there should be no loss. Ive done this a few times and it works really well. Again, just my opinion and experience for the sake of discussion
I let it air dry. I have done x-ray film several times and receive roughly the weight as Sreetips did here. My first try was using a length of 2x4 with a cup chiseled out as a crucible and a butane torch. My best weight came from MRI films To make any money your input cost must be less than your revenue. Sreetips, you can get faster removal by diluting your bleach 50/50 with distilled water. Stay away from the "thickened" bleaches.
I had to do some wastewater testing for an industrial permit at a college and one part was for the building for dental hygienists and nurses. Figure chemical treatment system along with silver recovery systems for the Xray and dental areas. Even in the wastewater pipes leaving the building I could detect silver. The worst part, the copper pipes for the drains from all the HVAC units. The pipes from the labs were glass and no problems with the chemical system.
Thanks for the Video, I have one question , what is the bleach? which chemical is it? please clarify to me and i want to recover silver from X-ray film.
Refining and these videos, have changed our lives. With the ad revenue from the videos, I don’t have to sell any of the metal. I’m thankful for what has been granted to me!
ooof i am kicking myself watching this, about 6 months ago i threw out 15+ kg of old x-rays I'd hoarded. this looks like a fun process, and damn, had no idea there was silver on them!
It's possible to still have silver in the gelatin, agar coating where silver was (which foams in NaOCl sol - Na hipochloride sol with free Cl2 solved faint yellow which is high alcaline too...) That yellowish foamy solution which tends to do a silver coloidal state... Solution must be boiled to dry and residue will contain Ag... Possibly...🤔💭😇
there is a some x ray film which is exposed by light but differ from used x ray film so this kind of x ray film only washing by naoh and filter then melt plus getting a product i think so because the silver is accumulated mainly.Say something and start this project?
Thank you so much For doing that.. Yes you demonstrated how to extract the silver and also gave us kinda a formula to go by when doing ut ourselves and wether or not its worth it to follow the project all the way through or not.... That's assuming that all x-rays are generally about the same in their silver content... I would love to invest to get started... But the way things are going right now.. I am building a gravity fed water filtration system.. So we can have clean water.. Things are so different anymore.. The carefree days have vanished.. These are different times.. I think a good water filtration system will be the smartest thing i have ever done... Even better than college.. Ha ha ha ha ha ha. Well the smartest thing Next to making colloidal silver.. Have a nice evening
By way the material you using to produce gold and silver is very cheap in egypt for example x ray film (chest) is 28 pound for one kilogram if you like I can bring to you contacts of egyptian exporters .
1 Kilogram of film will yield roughly 4 grams of silver. I don't know the pound/dollar conversion rate, but that comes out at about $2 worth of silver. A more reasonable price for the film would be something like $28 pounds a ton. But I suspect shipping costs alone would be far more than the recovered silver value.
I wonder, if having used glucose instead of saccharose you wouldn´t have gotten a better yield, since glucose has a reducing effect, which is also used in the Tollens probe when silver nitrate is instantly conversed to metallic (mirror) silver.
Hi, Industrial silver recovery is somewhat fascinating to me. I have recycled several thousand pounds of film for aprox. $0.15/lbs in the US. Simple mathematics on .5 oz recovery on 5 lbs film, there is not much value in secondary recycling. Years back, before recycling was popular, I used to have to pay to have film removed. My question is, would the same practices work on a volume of 500 lbs at a time in large drums of bleach and some time sensitive chemistry? I have a challenge for Sreetips. If I mail you 250 lbs of film at no charge, could you create a solution video of volume recovery practices and split the raw silver 50/50? (less the cost of raw chemicals of course) Let me know...
John, thank you for the kind offer, but I must respectfully decline. I am not set up to refine other people's material. I only do this as a hobby. I made this video to demonstrate how it can be done.
one thing you could have tryed when you did this few years back try and see if you could print on them with a laser and a inkjet printer. i have some that i did have and a laser printer did work you could see what it printed as the film had some type of chem that made ink and laser print stayed on it. next time you get some film next time try it b 4 hand and after then you could have 2 uses for them instead of binning them
Excellent experiment .....that's what science is all about...but FYI you could get the silver quicker by drying out the 1st sludge and smelting it with NaCO3 and borax then pouring into a cone mold.Commercially the film is shredded and dumped into a very large vat of caustic cyanide with much agitation and aeration then electro-refined and the cyanide is reused.Of course you don't want to bring cyanide into a home environment but this process is easily scaled up to handle large quanities quickly.
People that have a stack of x-ray films layin' around can do some reclaiming! I really hope there isn't anybody out there that has 5lbs of their own x-ray pics out there! Interesting process! Thanx bud!
the time you worked you did use is the chlorine bleach or no? am temesgen tenaw ,second mechatronics enginnering in Ethiopia,in my country such type of working is not common but i want to work because it is very useful and having the raw material in my country to work this extraction is vast this shows that or i mean there is silver deposit,so please help me in the form of telling the steps and the caution first let me tell you that am going to work soon 1. I prepared naoh,hno3,hcl 2.I presented the x-ray film 3.and different material for the sake of making it e.g like plastic bucket... 4.for the sake of caution that i will use when i work is the google glass and glove 5.in order to use the bleach i could not find it soon so i believe u will see and judge and tell me material equipments of u used when you work like bleach ....and as far as u know u tell me by far the best method if i could not follow the best method you would tell me the correct one and if you said ''USE A BLEACH'' i will use to get the best quality. HAVE ANICE TIME!!! JUST STAY BLESSED!!!
I used chlorine bleach to strip the films. Sodium hypochlorite dissolved in water is the same thing. Then I used lye and sugar to convert the stripped black material to pure silver metal. The first time is always the hardest.
interesting as an educational purpose ! it gives sense on the word "recycling", thanks for all your work, i also enjoy all you videos about gold refining
