Dissolving Gold in Mercury
HTML-код
- Опубликовано: 28 сен 2024
- Okay, so we are not truly dissolving the gold, we are actually forming an alloy between the gold and the mercury (called an amalgam).
This process is not only cool to look at, but it also is really useful to extract gold from ore. The gold-mercury amalgam can then be isolated and the mercury is boiled off or removed chemically. This leaves behind relatively pure gold.

A little warning for if you ever try to melt this gold is that the tiny crystals formed will trap mercury.
Do you have a PhD in mercury?
codys Body is half mercury half beeswax ;D
hmm interesting. Thanks for the warning!
But wouldn't the melting process evaporate the mercury away, or is that the point of the warning?
yes the gold will emit mercury vapor as it is melted which can be a problem if you are not expecting it.

"Mercury can combine with any element" *uses gold of all things*
Well historically mercury was used to extract pure gold from the ore that miners found during various gold rushes throughout the centuries. So it's not a random selection but a very appropriate one given the history of these elements together

Used to. Now they changed to other material since Mercury was proven to be toxic and in fact blamed for so many humam maladies.

@@j_respect5948 Dentists don't use mercury anymore. They use gold, silver, or most commonly, tooth-coloured composites (resin).
I am a big fan of your longer and more complex videos also, but i think these short, well produced videos would be fun to watch, especially for people who are just starting to get into chemistry, or don't have the time and motivation to get into complicated topics at the moment
It also lets me cover smaller topics that dont require more in depth explanations.
So this is where the shorts idea started.

The Mercury amalgams were the only popular option for dental fillings until recently when alarms were raised about their safety and level of toxicity so other Mercury free options were introduced which are considered safer and better looking. These include porcelain, glass or resin ionomers, and composites that contain either quartz or glass. Noteworthy the FDA never banned the use of the Amalgams and still declare them safe keeping it up to the dentists to use.
im 21, i have silver colored fillings from when i was a kid. is it likely they are mercury amalgams?

Thank you so much NileRed for mentioning that thing about dental amalgams. My mother doesn't want to do it and wants to live with pain in her teeth. I told her about it after seeing your video and she said she will finally get it done. I said "see my favourite RUclipsr recommends it".
Amalgam is very rarely used in dentistry any more. The effects of long term exposure to mercury were too worrisome..,
Epoxies are most often used for fillings.
@@neilolif thanks
We didn't use amalgam. We used Composite filling
I like this format. The smaller scope makes it easier to follow for engineers like me, as everything remains basic and straight forward. In your main videos, I am happy when I can pick up the big idea and some specific details - also great, but heaving a more digestible format is awesome.
I think I will keep doing it! I am going to try to do 1 short and 1 long one per week. We shall see if i am able to do that though.
sarowie; Dude!... I'm also an engineer (Electrical), so I know very well just how *stupid* we are, but you don't have to tell the whole world!
On a serious note, I got REALLY scared when you said you were going to keep doing shorter videos (with the way youtube works now, high quality, long but infrequent videos are going the way of the dodo), but doing both would be *SO* great, if you could actually keep up with such a hectic schedule.
Either way, I'll always keep watching. A shorter time allowance does restrict what content you can put out, but it doesn't intrinsicly change the quality of that content (as this video so nicely shows).
Your content is good content, and I'm convinced that will never change!
Also, I just want to say that, even as an EE, I still find all of your longer videos very well narrated and logically laid out, which makes them quite easy to understand.
Sure, at the start I had ZERO knoweldge of organic chemistry, so it was really confusing to understand the 'jargon' (like washing, drying, salting out, etc) and why the reaction mechanisms proceeded the way that they do.
But, literally, it just takes a couple of hours of googling (at most) to learn the terminology, the basic funtional groups, types of reactions, the most common electrophiles and nucleophiles, as well as how to draw and read the structures and the mechanisms.
After that, simply watching your videos (and reading the source literature for the reaction, if available) taught me enough to be able to follow everything that you do. Obviously, if it's the first time that I've seen a specific reaction, then I won't know anything about it; but I think that just makes the video even more interesting! It really doesn't impair my understanding of the content, since the narration is always good enough to explain what the reaction does, why he is using it and (if he has enough time in the video) how it works as well.
Keep up the great work Nile,
Your videos are Chemical Perfection incarnate!

@@NileRed sir I have some thing give to you pls co tact me.my English so week I can not express our emotion. But I send to you a powder you examine on lab and get result then call me but how I send to you .
Thanks for making this video. I have often wondered what it looked like when the miners from the old American west used mercury to extract trace amounts of metallic gold from ore as you mentioned. It would be interesting to know what process they used to then separate the gold from the mercury.
They heated it up because mercury melts at a much lower temperature than gold, the gold would melt and the mercury would evaporate away. The problem was a lot of miners suffered from mercury poisoning.
Gold amalgam actually has one quite old use. It has been used for gilding metal objects, it doesen't have to contain alot of gold so the amalgam is quite runny and can be aplied with just a brush. It sticks nicely to metal surfaces, then the object is heated to evaporate the mercury and that's pretty much it. Of course now we can apply metals with electro chemical techniques so there's no use for mercury-gold amalgams
Am I the only one that *really* wants to bite into that metallic blob. I think the texture of it looks super satifying...
At one time, gold amalgam fillings were popular. My wife had a few gold fillings in her teeth. It looks most odd, and I told her several times to get them replaced with modern white fillings, but she wouldn't do it.
Yep, which was kind of why I was wondering why he only mentioned silver. I remember that "back in the day we had gold fillings", but then there's a chance your mouth could get robbed for those gold fillings by unscrupulous people who would steal it to sell it for ill gotten monetary gain.
I think even the dead would get their mouth robbed of their gold fillings if the family didn't ask for them back before they got buried or cremated.
Speaking of the silver one, I had to get one in "that one tooth" since that tooth couldn't stay dry enough during the filling process for the composite to properly set.
You should play it in reverse... that would look cool!

This works under water and is a far safer way to handle the element Hg. No splash, no fumes.
It's always interesting to watch your videos, even though I'm not a chemist myself. Keep up the good work!

This is definitely hypnotizing me.
instead of mercury, you should have put a teleporter under the gold, and it should take that gold to my house.
4:59 - "I put the entire vial in a toaster to dry out the gold."
Of course. You're not a real scientist unless you use a toaster to dry your metal.
frequently gold panners will throw a nice size ball of mercury to the bottom of their pans. the fine leafy gold obviously does what we we in this video.
its a highly frowned upon method but works very well
At what saturation point does it take (with wither Au or Ag) to stabilize the Hg so it's no longer biotoxic?
lohphat It will never be truly non-toxic. Mercury metal isn't the worst, only vapours are seriously toxic, you can drink it and be fine apart from what gets into your lungs. But an amalgam will always emit some vapourand be potentially hazardous.
Edit: As some people correctly stated below, none amount of mercury is truly non-problematic, yet one must remember that very small amounts of mercury will not cause too much problems and may be considered safe like the minute amounts released by an amalgam. Probably.
Martin of Gliwice whether they're right, or they're wrong, for many years dentists have been sticking mercury amalgam fillings into people's mouths.
John Ratko Yep. I have one. No prohhhhhblahh... çcv&v'' I'm fine.
It depends on what you mean by 'toxic'.
If you're like most people and are only interested in life-threatening effects or very large, sudden and easily observed decreases in mental capacity, then mercury really isn't all that toxic in its elemental form.
You could get mercury fillings in all of your teeth, dunk you entire hand in mercury every single day and break a fluorescent light bulb about once every week (without doing anything other than opening a door or window so the vapours can slowly escape) and you will very likely never see any of the effects that you're worried about.
If, however, you are like me (luckily, very unlikely) and are concerned by even low levels of cognitive disfunction, then... you're prettt much screwed.
There is NO recognised minimum exposure level that is 'safe', since mercury is an accumulative biotoxin and also *VERY* difficult, if not impossible, to safely remove from the brain.
Basically, your brain will actively absorb any mercury that happens to be in your bloodstream and effectively 'cement' it into neurons distributed throughout your brain.
problematic are mercury compounds like methylmercury and mercury salts like the mercury nitrate he produced.
methylmercury accumulates in the food chain, the top predators get the most of it... like humans who like to eat predatory fish like tuna. If somebody fears dental amalgam, he should never ever eat wild fish from the ocean. ;)
and mercury nitrate is the stuff which was used to make felt from fur and caused the mad hatter disease. The real cause was non-existent workplace safety. Toxic chemicals? no problem, the workers will breathe them away.
then there is dimethylmercury, that stuff is so toxic that it will kill you if you touch it with or without rubber gloves... this is the scary stuff that makes everybody nervous. And because "dimethyl" is such a complicated word, everybody reads it as "mercury" and that is why everybody is scared of elementary mercury.
mercury(II)oxide was used as kathode in mercury-zinc batteries, these were a problem because they ended in the trash, getting burned or dumped into the landfills.
elementary mercury is such a nice toy, you can play with the droplets and there is no need to fear its toxicity. You can have a big blob of it in your hand and feel its weight. Just like you can do it with a piece of lead. Lead is also toxic... And now some people think "oh no, the mercury vapors"... yes, mercury vapors are also toxic, but they are heavy too! If you have a open glass of mercury, the vapors will sit on top of the surface and keep the rest from vaporizing... if the vapors escape, they fall down on the floor and if the floor is porous, it falls into or though it. It could be harmful for ants in your basement.
Some may think that there was a chinese king who died of mercury poisoning and he had a lot of elementary mercury as artificial rivers and ponds. Thats right, but there were these quacks who made an elixir of life out of cinnabar (HgS), they promised immortality and made him drink the kool-aid.
The fear of mercury can be so big, that some people have tried to remove it with chelating agents and got in big trouble caused by the side-effects. A chelation therapy removes not only that scary mercury, but it also removes other elements/minerals like calcium which then can cause life-threatening heart problems or spasms of the vocal cords (you suffocate and die)...
And don't believe anything what i said, do your own research because i am just a random person on the internet. But everything i said can be used to search with google for some trustworthy sources.
Amalgamation with gold was used in ancient China as a method of coating for the bronze Buddha statue to make it more shiny. The mercury was vapourized after heating so the gold stayed clung to the statue.
Why is watching murcury absorb gold so satisfying
You should try this with more metals.
I will! I will do it with aluminum, sodium/potassium, silver, etc.
NileRed, Aluminium + mercury has been done many time before, though maybe see if aluminium foil (the thinnest type you can find) will do anything similar to the gold effect. Also, might be interesting to see if NaK will dissolve gold, silver or other "unexpected" metals.
I especially would like to see it done with copper.
Also, what would happen if you amalgamated it with cobalt or nickel (apparently iron is resistant to it) and held a magnet to it?
i'm waiting for platinum and osmium
cobalt and nickel are also resistant to it though it does give me an idea for an even heavier ferrofluid.
Once, when I was a kid, I wanted to watch the mercury in a thermometer rise up through the tube, so I held the end of the thermometer in a flame. Unfortunately, the thermometer broke instantly, and also unfortunately I was using my grandmother's gold cigarette lighter. It wasn't till later when I got in trouble, that I realized the mercury had fused to the lighter and discolored it.

"No socks were hurt making this video"
Gold leaf is super interesting. Mercury has been used to help recover a few micron sized gold dust. Unfortunately this process has poisoned many people as distillation of the Mercury puts off Mercury fumes. Still a very interesting process.
Research the TR-3B right now. It's our first vehicle reverse engineered from the crash in Roswell. It flies by heating mercury to a plasma and spinning it at 1.21googleplex rpm.
Learned that from a dot gov page.
“Squeezing out” the liquid Mercury was so incredibly entertaining
Now this mercury is more costly then orginal gold 😂😂
“Anyway I was so amused with it I did it 23 more times” should be a TikTok sound
Very Interesting, good narration. I subbed Thank you for time well spent!
To the Sages and the Alchemist, liquid mercury is the basis for all metals, before other elements mix with it to form other base metals. Also it was mercury that was used to make gold. It is also said that the process of making gold from mercury is also the same process of transformation of the soul and body/philosopher stone.
Can we get the amalgamation series now?
That’s interesting because gold is supposedly indestructible. You can melt it but it doesn’t destroy it. If it it’s at the bottom of the sea it doesnt dissolve or corrode, rust or tarnish like other metals
So ... if phos vs cinnabar ever happens then phos is f*cked.

So they'll glow and form a giant woman
@@LostSwiftpaw i didnt know i needed this
not at all tho, since phos arms are made of both gold and platinum and i think mercury doesnt react with platinum
did.....did you just sum up the whole last chapter?
I remember when I was in the eastern part of Peru in 2011 for school this was a much talked about environmental problem - the small-scale itinerant miners would dig up tons of sediment from the bottom of the Madre de dios River, sift it over huge sluices and then dump lots of mercury into the fine sediments to... And then simply evaporate the Mercury off to leave the gold. Of course this causes enormous amounts of mercury vapor pollution and is in fact one of the largest sources of mercury pollution in the world after coal power plants.
The mining also causes damage to the river ecosystem directly due to stirring up large amounts of sediment... And some of the miners also Venture into the woods to cut down rainforest trees and dig up the land to form new ponds where they do the same procedure as in the river.
The government had been trying to stop them with laws and sporadic enforcement but it was impossible to stop all the miners. I even heard there were military operations to blow up some of larger mining barges. I remember a large government complex in the city of Puerto Maldonado was a charred ruin, my friends told me due to riots over new government regulations and enforcement on mining.
Mercury is a very stable metal, with seven stable isotopes; it is second only to tin, which has ten stable isotopes.
woah! black hole effect cool!
suddenly that houseki no kuni chapter makes much more sense

I was honestly just curious how this worked, because I remember my uncle telling me how the mine my Grandad used to work for, used the mercury recovery method (obviously) for recovering access gold. This was the “White Pine Mining company” that was shut down in the late 90’s. And O remember my uncle also saying that my Grandad helped design their floatation system. (For separation of the mined ore).

Now I've led to gold
Hey, I saw a video in Facebook where a scammer (buyer) puts unknown substance (probably mercury) in someone's jewelery in an attempt to lower the price of the gold necklace. Some parts of the necklace became brittle and some parts got dissolved like rusty metal. So the owner brought it to a jeweler to fix it and he used flame torch to remove the mercury and solder broken parts. So I assume the mercury became gas? Isn't it super toxic when it becomes gas?
Yes it is
The method used in this video is extremely toxic. I would not advise anyone to follow this method, or in fact to even consider "playing" with Mercury at all. There are no "cautions" given about the danger of using Mercury. The fact of the matter is, Mercury can and does vaporize at and well below room temperature. It does not have to be heated to vaporize.
I saw no cautions about using protective inhaling respirators. Inhaling Mercury vapor is the fastest way to get Mercury into your system. Mercury is cumulative and is not dispelled from your system without going through a "Chelation" process.
Working with Mercury requires a rigorous safety training process, which I have gone through as a lab technician for UCLA. The dangers associated with working with Mercury for an untrained person are simply not worth the risk. The toxicity is not to be underestimated. There are dangers that most, if not all, untrained people are unaware of cannot be taken lightly.
Putting something like this on RUclips is highly irresponsible and has the capacity to cause great harm to others. I would highly suspect that the work area this RUclipsr worked in is highly toxic. A Mercury sniffer instrument would probably show Hg levels that are off the scales of the measuring devise.
@@jamesfoley5335 I've seen a video where under a uv light, mercury vapor can be seen like a hot coffee with smoke

Couldn't those teeny drops of liquid mercury spilling all over the place still have small amounts of gold in them, and thus, by letting them escape, you're losing bits of gold?
