Separate mercury from gold jewelry


Contact with mercury instantly ruins jewelry, but boiling it in coconut oil can fix it! Read on....

++

Q. I got mercury from a broken thermometer on my gold wedding ring, and it bonded to the gold. Jewelers won't touch it. I asked a chemist in my area what to do. He suggested silver cleaner which didn't work. I'm obviously not a science expert; I'm an elementary school teacher. I've done some reading about nitric acid. Can I put my ring into plain nitric acid and separate the mercury from the gold? Any other piece of jewelry would be replaceable, but my wedding ring means far too much for me to replace it. I'm afraid to wear it with the mercury still on it. I don't know what to do. Can you help me?

Thank you,

A. Hi Ms. Wilson,

Your reading is right about nitric acid; you can also heat that ring at your home, but after heating or putting in nitric acid you have to clean (polish) the ring.

Good luck,

A. The mercury will migrate into the gold similar to a splash of water migrating into dry wood. You will need to autoclave (outside extraction!) the ring at a temperature above the boiling point of mercury and below the softening point of gold (to be safe I would recommend at least 3 days).

A. Nancy, just like you, I broke a thermometer yesterday and my wedding rings turned silver in color. I have not talked to my jeweler yet (who is a good friend of mine).

I told my husband about the rings and he tried to clean the rings in our jewelry cleaner. Big mistake, because my husband put some other gold jewelry in with it and now every thing in it is silver.

What I did do is this. I started my propane burner and boiled a pot of water. Mercury evaporates into a vapor and into the air. Boiling mercury is toxic because the vapors can go into the air and be breathed into the lungs. Gold miners used mercury to pan for gold. Then they would boil the mercury off the gold and tumble it. I was told there isn't a significant amount of mercury on the rings but wear a face mask the you can buy in the medical department at Walmart.

My husband and I boiled a couple pieces of pieces last night, to experiment with, for about an hour and they look like brass that needs to be shined. Before I do my rings I am going to talk to my friend to see if he will extract the stones before I boil it. My neighbor said I could put my rings in his tumbler (Used to polish brass gun shells for those who reload their own bullets). I can keep you in touch with what happens after wards. I just got married a couple months ago and like you, my rings mean a lot.

Sorry if this seems a little scattered. I read your question and was able to relate. It is a shame to think there isn't any jeweler who can help.

Like you,while we were on a job, we found a broken thermometer,so we quickly cleaned it up and the mercury spill from the broken thermometer, and I to had it attract and go onto rings, my wedding rings, and 15 year anniversary ring, before having a chance to get the gloves on. On my wedding rings, the mercury ate the gold and my ring just fell off my hand, my anniversary ring turned silver, and started cracking,we pulled out a deactivating kit to clean my rings like we do in most emergency cases we do for work and sealed them in the bags,because if they get to warm they will send off fumes,even with the heat of the sun, to which ARE DANGEROUS and can cause serious health affects. after several days my wedding bands started falling apart in the bag. My rings to are very important to me since I have had them for over 20 years. I took my rings in the sealed bags to 6 jewelers hoping someone could help me. EVERYONE said no, when mercury is heated, even when it is boiled, it causes fumes and a health risk. You can get further information on the department of health and human services website: http://www.atsdr.cdc.gov/toxfaqs/tf.asp?id=1195&tid=24

GOOD LUCK. jmk

Thank you for that sobering link, Janet. Doing some web searches I see some jewelry shops in England who will repair this mercury damage, but I've found none in the USA advertising to do it.

Obviously, people will try to save their priceless heirlooms no matter the personal and environmental risk -- desperate people take desperate chances. But the process really should be done by trained professionals with proper facilities rather than by amateurs-- this refusal by the jewelry industry to be proper stewards, and just wash their hands of the issue, is a serious problem! If anyone knows of such a service, please advise.

It's All in Your Head: The Link Between Mercury Amalgams and Illness

Q. While I was changing the bladder of blood pressure measuring instrument some mercury accidentally felt over an gold ring and slowly its colour changed to silver then after 24 hours it got back to its original colour but I am afraid whether some amount of gold is lost in the reaction.

Q. Surprised to find this page. This too, happened to my wedding rings several years ago. I've kept them but after reading this, I guess I need to keep the diamond and throw away the bands? Is that the only safe thing to do?

Thanks,

Carol Ldeleted

+++++++

A. Your problem can be solved easily by heating the affected area with a butane lighter. The ones with the blue flame would be best. The mercury which has dissolved the gold and other metals to form an amalgam will boil off leaving the original metals as they were originally. However, if in the process when the gold was dissolved, it's shape was changed, correcting that would be a separate problem.

It has been noted that the fumes from the mercury vapor are dangerous. While this is true, if proper care is taken, the risks are minute. The amount of mercury on the ring is very small. You should be able to avoid breathing the mercury vapor if you heat the ring outside and do it upwind. Use a piece of wire or coat hanger to hold the ring while you heat it. Also, you may try to hold you breath for 20 seconds or so while heating. Reheat until complete.

Some people will try to scare you to think that you will drop dead from this exercise. Well consider that alluvial gold miners heat mercury gold amalgam every day with little protection. During a recent study of miners in Indonesia, the study results were surprised by the low levels are mercury found in the miners blood. I think if you do it one time, you should be able to avoid exposure. Just to be safe, don't do it if your pregnant. Give the job to your hubby.

Oh gosh, what about polluting the environment with the fumes? Well again, that is of no significance to the environment. According to the EPA, the USA coal industry releases about 157 TONS of mercury into the air every year (1998 data). Even still, nearly half of mercury in the atmosphere is released by natural processes such as volcanoes. Therefore, your milligrams worth of mercury is nothing to worry about.

Let us know how you make out.

Q. Hi I've read this very interesting blog. I also have mercury on my 5 rings after the thermometer broke, but decided they can stay silver after I have tried everything possible to get the gold back.
Will it be dangerous to wear the rings?

Basic Chemistry folks: Mercury coating Gold => mercury & O2 + heat => Mercury oxide, a stable stable compound and you just polish it off the inert Gold with whatever you favor.

Like most of you I was playing with a thermometer and got mercury on my wedding ring I've been wearing for 20 years... so it was kind of important to get it off, but the more I polished the more I heated and moved the mercury around and it never came off.

To get it off I finally just bent a cloths hanger leaving the bent part in place to put my ring on. I then turned on the good old LP kitchen stove and heated the ring to a dull red, took it out of the flame and let it smoke a bit. When it stopped smoking I put it back in. I did this over and over seven or eight times until the entire ring was a dull black (mercury oxide).

Then it was just a matter of polishing the stable form of mercury off of the inert gold. I haven't used my polishing rouge yet but Crest and a sponge does a pretty good job until I have time to use the rouge and make it mirror bright

I read where you cut a spud in half, hollow it out to the size of the amalgam (rings?), then tie the halves together with a piece of wire. Chuck it into a fire and let it bake. After awhile, fish it out and remove the gold/rings. To recover the mercury, bake it some more (to charcoal I presume), then crush and mix with water in your panning dish. I guess the flesh of the spud must trap the mercury. Sounds good to me.

I had a similar accident in a lab. a little drop of mercury landed on my gold ring and within a few minutes the entire surface of the ring got coated with mercury. I obviously panicked and approached the chemistry professor of my school for advice. he calmly took the ring from me and dipped it in an acid (not sure which kind). all of the mercury disappeared within no time and I was unable to notice any discoloration or other blemishes on the ring thereafter. this technique in my opinion is safer to the metal as well as health.

Q. Hi

My wife's Gold ring was getting discolored and getting patches of white color on it. We were wondering what must be the reason. When we checked her bag, traces of mercury was observed in her bag. The gold jeweler told us its because of the mercury.

Does mercury changes the color of Gold from yellow to white?

What is the remedial action when it has become white?

How to completely remove the mercury from the bag?

Thanks,
Deepak

A. I dropped mercury on my gold ring for the second time :( , here in India they use 100 % coconut oilamazoninfo to revive the Gold; didn't believe my grandma! However, tried it and it works trust me it does, all you have to do is drop it in coconut oil and boil for a 2 mins or more ... but do take some precautions when you try it and MERCURY IS EXTREMELY DEADLY !

Q. Hi, I have an 18 carat yellow gold and platinum ring. I broke a thermometer the other day and removed the mercury, touching it with a paper towel. One 18 karat yellow gold ring turned slightly silver on the back side and my other ring, also 18 karat gold turned entirely a dull matte silver color. I have tried polishing it with a polish cloth and even with a Dremelamazoninfo and jewelers polish, it is still silver color but now polished. Any ideas to get the yellow gold color back in my 18 Karat yellow gold ring? baffled and bummed. thanks

A. I did this experiment, I had a thermometer to throw, so I took out mercury and touched my ring to it :), by then I didn't read this page, as how difficult it is to take it off :)

Guys if the amount of mercury is less, than don't worry.
Get some coconut oil simple to find for Indians - Parachute coconut oilamazoninfo.
then heat the oil, and dip your ring in it.
leave it for some time.
keep watching it, its really quick!
and if needed repeat the process.

the polish of the gold will be lil off, but that's not a big deal!

cheers!

Q. My wedding ring is 14K yellow gold however, the other day it turned a silver color.I was researching your site for a reason when I noticed a reply on March 31, 2008 you wrote to a gentleman who said he had broken a thermometer. YOU EXPLAINED TO HIM HE WAS LUCKY BECAUSE MERCURY WILL RUIN YOUR RING!

I too broke a thermometer the other day,I cleaned up the mercury and disposed of it properly but now my ring is completely silver! Does this mean my ring is ruined? What exactly does that mean, "ruined"? Will the gold color ever return?
I am confused. Please help.

A. Hi, Rose. Mercury forms a stable amalgam with gold. I have heard of cases where the exposure to mercury was so low that the ring turned back to gold, as the mercury diffused in, but don't count on it, and you don't want to wear a toxic material like mercury. Take it to a jeweler to see if he will drive the mercury out. If not, you will have to decide whether you want to follow the instructions that others have offered. Good luck.

A. Okay, I had the same thing happen with my silver ring. I found one jeweler who will work with it. They dip the ring into cyanide salts and it extracts the mercury. I have checked with two chemists who have agreed it should work. Not sure if they have to remove the stone first though. I'll let you know how it comes out. Its worth a shot.

Q. It seems that there are 3 occurrences with mercury getting on the gold. One is for the mercury to adhere to the gold, the second is for the mercury to turn the gold silver, and the third is for the mercury to eat the gold, which is what happened to me. Can anyone tell me what the difference is that caused these different reactions. My ring was 18k, does this make a difference.

Also I am not being funny, but where did the gold go to? I too broke a thermometer in my hand and saw the gold disappear before my eyes. I now just have a shell of the original band.

Thanks
Robin

A. Hi, Robin. I'm not an expert on this matter, but I don't think the reaction truly differs, but is simply a matter of degree.

Mercury and gold form the amalgam you are seeing, and it will happen every time you spill mercury on a gold ring. It is a reaction like making a metal alloy, but it happens quickly and at room temperature. Mercury also forms amalgams with the silver and copper content of the ring, so I suppose the results could look a bit different based on the karat content of the ring.

Mercury vaporizes as a gas into the air, and we have theorized that if mercury was in a sort of enclosed space like a drawer, the air could have enough mercury in it to turn a gold ring to a silver tone on the very surface, but that as this very tiny amount of mercury began to diffuse through the whole ring, the amount would be so low that the ring would turn back gold again. There seems to be some anecdotal evidence that this has happened to people, but I don't know about any actual research on the subject.

Q. I too had broken a thermometer on my wedding ring a couple days ago. Can anyone tell me if the ring is put in coconut oil or water and heated if the diamonds/stones have to be removed first? I really want to remove the mercury. I would be heartbroken if my wedding ring is ruined forever!

A. Hi, Julie. I'd hunt hard for a jeweler who will fix it since dealing with jewelry problems is their specialty. But if you can't find one, avoid the thermal shock of dropping a diamond into boiling liquid; hang it in the pot while the liquid is still cold.

Plain water won't work well if at all; I have no personal experience with coconut oil, but three previous readers have reported that it works.

hello, my grandmother was a gold miner and she used mercury to separate her gold.she kept her mercury in a gun case. since her passing my mother found her mercury and has been using it to separate gold that has been panned. my mother showed me a vile of what she said was pure mercury. she told me to shake it to see if I could see a gold nugget inside. so I shook it and put it down on the scale and silver balls started rolling off. come to find out there was a crack in it and mercury was on the outside of the bottle. she is not being very careful with it. I have seen silver mercury balls on her jewelry box and etc, my concern is my 3 young children in the house, I don't want them exposed. am I being paranoid or is contact that deadly? please put my mind at ease.

Hi,

When I was a boy lots of kids played with mercury quite a bit, so it's clearly not universally deadly. At the other extreme, the phrase "Mad Hatter" derived from the fact that hatters who used to work extensively with mercury would get mercury poisoning. Dangers are all relative. All loose mercury should be cleaned up so it does not emit mercury vapors, and your mother should know that mercury exposure is bad for you, and should mend her ways, especially with small children around. Beyond that, some people would urge you to hire a specialist to decontaminate the house, but based on how much mercury I've seen, personally I wouldn't pay for professional decontamination. Good luck.

I have had the mercury from my 3 rings removed by the London assay office. After breaking a thermometer and my rings first turning silver then dull gold. I asked advice from a jeweler and he said nothing could be done. I called my insurance company for help and they said that they would send in a assessor to quote replacing the rings. As I have had my wedding ring for 40 years this June I just wanted them free of mercury.Someone else suggested the Assay office in London have a lab and they may be able to help. A phone call to them confirmed for a small fee they would burn off the mercury I posted the rings to them and to day I had a phone call to say that the rings have successfully been decontaminated, I paid them by card over the phone and anticipate their return to me ASAP...

I note a number of people have highlighted the toxic nature of mercury. Whilst it is not ideal to inhale mercury vapor, I feel the need to highlight that the UK government, plus others, are quite happy to still use mercury for dental fillings.

Finally mercury is found in fish. A food we are encouraged to eat.

All in all, this does suggest that very low doses of mercury cause little harm.

thumbsup2From this page, I got the solution. The gold jewelry was kept aside the Mercury tablets (to be kept inside the grain). The jewelry was kept in a plastic pouch in the grain tin. The jewelry was not in direct touch with the mercury tablet and also the tablet do not contain the real mercury in its original form. Even then, the jewelry turned white to some extent. After, getting solution from this page, the jewelry was boiled in the Coconut oil for two/three minutes, thereafter, allowed to cool down and washed with soap leather. To my surprise, the original gold shining returned. Thanks a lot.

A. Hi. I work in the Dental field and all of my co-workers are indians with full golds around their body :-)
Anyway, one of my workmates tried to use our old BP Apparatus and it seemed that it was broken so mercury went directly to her wedding ring covering 75% of it. She cried the whole morning because she recently just got married :-(

Fortunately, one of our Dental Interns is so bright. She rubbed this ALGINATE (powder used to take impressions or models for teeth) towards the ring and it went back to its normal condition in just few minutes! Just go to a nearby Dental Clinic and ask for Alginate or Pumice powder. Afterwards, just a little polishing is needed. Hope this helps :D
