- How Mercury is Made
Ancient Hindus had the knowledge of mercury before 2000BC. Mercury has been found in Egyptian tombs dating back to 1500 BC. In about 350 BC, Greek philosopher and scientist Aristotle described how cinnabar was heated to extract mercury.
The process for making mercury hasn't changed much since Aristotle first described it over 2300 years ago.
Cinnabar ore is first brought out of the mine using drilling or with the help of explosives. It is broken into smaller pieces with the help of cone crushers. The crushed ore is ground even smaller by a series of mill. Once the ore is finely powdered, it is then fed into a furnace or kiln to be heated. The heated cinnabar reacts with Oxygen in the air to produce Sulphur Dioxide(SO2), allowing the mercury to rise as vapor.
The mercury vapor rises through the exhaust along with Sulphur Dioxide and water vapor. The mixture of gases passes through a water-cooled condenser. Mercury which has a boiling point of 357 degree Celsius, is the first to condense into liquid, leaving the other gases to be vented out.
The impurities are removed by filtration; leaving a liquid mercury that is 99.9% pure. Higher purity can be obtained by several refining methods. The most common refining method is "triple distillation". The ultrapure mercury commands a premium price.
Mercury is stored in steel flasks or glass containers.
Mercury being the only liquid metal, possesses many unique characteristics like good electrical conductivity, a very high specific gravity, high surface tension and a very high coefficient of thermal expansion.
It finds applications in gold and silver extraction, electrical and electronic switches, thermometers, fluorescent lamps and dental amalgam fillings.
But unfortunately, mercury is highly toxic to humans. Due to which, its use has severely declined over past 30 years. Mercury is still an important component in many products and processes. Although its use continues to decline, improved handling and recycling is expected to significantly reduce its release to environment and reduce its health hazard.

(1) Mercury metal can not absorb through the skin in any significant amount unless you have open wounds.
(2) Mercury metal does not make enough vapor at room temperature to be dangerous.
(3) Mercury metal also can not absorb through your digestive tract in any significant amount.
(4) Mercury metal is not very reactive and therefore does not react with other chemicals very much either.
(1) Tests have been done on this subject, and no evidence has been found that mercury metal absorbs through your skin in any significant amount. Also, its just dumb to say that mercury metal absorbs through the skin, since all things absorb through the skin in some amount or another. so, yeah it technically does absorb, but so does basically everything else on the planet.
(2) The amount of vapor mercury metal makes is comparable to that of cooking oil. And, last time I checked, people said "oil doesn't even evaporate". To measure how much something evaporates people can find the vapor pressure of that substance. Vapor pressure is just a measurement of how much pressure something builds up when its in a sealed container. And as it evaporates it makes little particles of that substance floating around inside of the container, making it slightly higher pressure inside. The measure of this pressure represents the amount of vapor the substance makes. Mercury metal's vapor pressure is 14,000 times LOWER than that of water. That, combined with the fact that mercury vapor is very dense and sinks in air, (and stays away from your head, which is where you breathe from) means that it is not a significant threat.
(3) Tests have been done on this subject, and no evidence has been found that mercury metal absorbs through your digestive tract in any significant amount.
(4) Mercury metal sits right next to gold on the periodic table, gold being the second most inert (unreactive) metal on the periodic table. Gold sits right next to platinum, its the MOST inert metal on the periodic table. Mercury is not very reactive and has been demonstrated so through many videos on TH-cam, where people show mercury metal. When its pure its always shiny and silvery and does not quickly tarnish like many other metals such as silver.
[This means that mercury metal can not be considered "highly dangerous" because it does not align with the definition of those words.]
[Just take a look at Cody'slab or Nilered, these TH-cam channels clearly show what I am talking about. Neither of them wear respirators. One of them is a professional chemist and the other grew up in the country with a mercury mine with his parents, and knows how to handle it properly. And both of them are adults.]
1) wrong, mercury can absorb through your closed skin even through latex layers, this has been confirmed by death
2) all mercury vapour is dangerous
3) mercury absorbs through skin and is absorbed into your bloodstream, including inside your body.
Giving incorrect advice is dangerous. Hopefully people know listening to advice on the internet is silly.
@@matthew4107 *EDIT/NOTICE: (the above comment needs to be updated, and re-phrased, but for some reason pinned comments cant be edited)*
what this comment was before I edited it: mind if I chat with you about this? you seem pretty intelligible.
@@matthew4107 yes, giving incorrect advice _is_ dangerous, and what makes you so sure you're the one giving the correct advice?
before I start, you are confusing "elemental mercury" with "organic mercury" they are *entirely different.* in this context we are exclusively talking about elemental mercury.
there are very large differences between them, so don't conflate the two. the word "mercury" when by itself is synonymous with elemental- (pure) mercury. calling an organic mercury compound just "mercury" is like calling glass oxygen.
to start, you said: *"wrong, mercury can absorb through your closed skin even through latex layers, this has been confirmed by death"* no, that was dimethylmercury, just because it has mercury in the name doesn't mean its automatically mercury. you are clearly lacking significant chemistry understanding to make such a rookie mistake. btw you are quoting the incident where Karen Elizabeth Wetterhahn touched dimethylmercury.
next you said: *"all mercury vapour is dangerous"* yeah, and all carbon monoxide is dangerous, so therefore we can conclude that we must never use cars and never start a fire again, because they make carbon monoxide, right? well obviously no, because a _tiny amount_ of a toxic gas is pretty insignificant. in general mercury metal does not make much in the way of vapor. at room temperature mercury metal is a whole 600F+ degrees away from its boiling point, so it really wont evaporate much. for comparison, at room temperature the vapor pressure of water is 23.8 torr (torr is a measure of pressure) but the vapor pressure of mercury metal is only 0.0017 torr, aka *14,000x less vapor than water makes!* its vapor can only even be *seen* using a highly sensitive ultraviolet light setup. mercury makes hardly any fumes at room temperature. where you get into trouble is when you live somewhere hot, and there is little to no ventilation. if that were to happen, the mercury would evaporate much faster, and wouldn't dissipate, causing a more serious hazard.
next you said: "mercury absorbs through skin and is absorbed into your bloodstream, including inside your body."
technically, yes, but so what if it absorbs? as long as its very, very _slow,_ (which it is) then it doesn't really matter. people tend to tunnel vision on the fact that mercury is toxic, and ignore the equally important fact that the absorption rate is so slow that skin contact wont be able to absorb mercury much faster than your body can repair and remove the mercury. in the case of touching mercury metal, the rate of absorption is astronomically slow, you would have to hold your hand in mercury metal for days if not weeks at a time to notice any effect. touching mercury briefly will not poison you. and as far as I know, nobody has ever died just from _touching_ mercury.
@@Metal_Master_YT Correct i was referring to the sad and educating story of Karen W.
You state many confuse the two (organic and compound) yet in your Broad statements you clearly did not explain the difference!!!! Your statements to someone who does not know anything about mercury could lead to fatal injury could it not?
My statement of 'All Mercury Vapour is dangerous' is not incorrect, and you seem to of only pointed out 'metal mercury' produces not much vapour, yet, that vapour is still dangerous. i am not commenting on what makes mercury vapour, how it comes into its form or in what quantity only that the vapour made from all mercury is toxic, which it is.
you make a slightly misleading statement regarding ingestion ''Mercury metal also can not absorb through your digestive tract'' this statement can be misleading and dangerous, you will say that you stated 'in any serious amount' or that it wont be enough to cause harm, however, again, you seem to ignore the fact your placing BAD and MISLEADING advice on the internet either to possibly harm others, or, end up in this discussion so you can sound like you know what your talking about??? when the truth is, i am saying your advice is dangerous and not 100% correct.
just because something doesn't produce much dangerous toxins does not make it ''that mercury metal can not be considered "highly dangerous"'' Mercury can kill, in all forms organic and compound, scenarios change, but it CAN kill. as much as Arsenic clearly isnt dangerous poison as smokers consume such a thing daily yet dont immediately die, its still classed a poison.
I'm glad i got you to better explain your statement, even if still slightly twisting words to your strange aim of fooling someone.
@@matthew4107 I'm not trying to fool anyone, people exaggerate the deadliness of mercury metal, and confuse it with its compounds, I'm trying to un-fool the people who believe these lies. there aren't any facts to support that mercury metal is as deadly as most people make it out to be, you can check.
*"You state many confuse the two (organic and compound) yet in your Broad statements you clearly did not explain the difference!!!! Your statements to someone who does not know anything about mercury could lead to fatal injury could it not?"* I am not responsible to make everybody safe, or make their read easy. you can' expect me to explain this complex topic as though I was talking to a child just so you can be satisfied, that is _unreasonable._
*"My statement of 'All Mercury Vapour is dangerous' is not incorrect"* yes, but it makes everyone think it will kill you if you breathe near it, so I clarified. you keep mentioning things that are technically true, but on such a small scale, that simply saying "the vapor is dangerous" is unintentionally deceptive.
*"you will say that you stated 'in any serious amount"* yeah and I will be right, and it's completely reasonable too, and does not _require_ further explaining, that is what your own research is for. *"however, again, you seem to ignore the fact your placing BAD and MISLEADING advice on the internet either to possibly harm others, or, end up in this discussion so you can sound like you know what your talking about???"* firstly, that's not why I'm doing it, earlier I told you my intentions: *"people exaggerate the deadliness of mercury metal, and confuse it with its compounds, I'm trying to un-fool the people who believe these lies."* secondly, my information is true to the best of my knowledge, so I'm not harming anybody, and its certainly not misleading anybody. you seem to have this core presupposition that I am wrong from the beginning, please stop it with that. correct information is not bad information for goodness sakes.
*"just because something doesn't produce much dangerous toxins does not make it ''that mercury metal can not be considered "highly dangerous"' "* well, actually yes it does, that's precisely how that works. *"Mercury can kill, in all forms organic and compound, scenarios change, but it CAN kill."* yes it can, and so can most everything, _that alone simply cant determine if something is dangerous._ *"as much as Arsenic clearly isnt dangerous poison as smokers consume such a thing daily yet dont immediately die, its still classed a poison."* yeah the arsenic in cigs are classed as _poison,_ but not "highly dangerous" Einstein.
Anyone else randomly get curious as to where mercury comes from?
cinnabar, (mercury sulfide) is mercury ore, you mine it like any other metal.
It's distilled.... what I find fascinating is to how they even thought up the process thousands of years ago
Yes, I just saw a video of an anvil floating in mercury because it’s so dense. After watching, I finally wondered where it actually comes from and now I’m here!
Yes i was just doing nothing and this popped in my head, relatable
That's why I'm here!!
Looking forward for more such videos on different elements
Amazing facts on mercury i never knew before
can you help me? i tried to extract gold from ore, i make quartz jelly from naoh with some calcium as binder, give them h2so4 thus produces silicic acid and i dried it.
finally i put aqua regia i simmer them till i supposed traces of hno3 gone, but suddenly i saw silvery white bubble at top of yellowish chloride complex i assumed when almost boiling, it was silvery white speck when i took out
can it possibilty of mercury or just other precious metal? i dont want to mess with mercury whatsoever i chose ore carefully that indicated contain any minimum of mercury
thank you best regards
1:50 starts, you are welcome
Thank you
Great video... Thanks for sharing

I remember trying to smash a thermometer with Mercury in it when I was a kid.lol I loved the 80s finding stuff like that on a bit of ground we would play sodies on
Keep going and keep growing
Ok so now I have more questions. Just wondering if mercury is conductive? I assume so. If it is how can it be applied/used? If it was energized somehow would turn into a vapor, burn away, or stay in its current state?
Thank you for the very detailed video.
Germany was using mercury in da bell experiments
Die glocke is exact name was supposed to be anti gravity tech
Mercury got a hit job and people scared to use it after this
@@deepnurmom1737why did people scared after using that, Instead Happy founding Good technology
It sounds like you’re recording the audio in a restroom.
Mercury is one of the 7 metals of antiquity
Just wondered what was mercury exactly found this ...thks interessting ✌ going to make my electro magnetic mercury engine now
So mercury is mosty mined from an ore called cinnabar, cinnabar is where the colour and pigment vermilion come from......cinnabar and vermilion are the same thing, god damn game freak there's all these colours and you use the same one twice?
Informative vedio
Very good informative facts
Interesting video. Thumbs up 👍👍
very interesting and informative video
Ohhh just fantastic👌👌
Enjoyed a lot👍
Nice information
This is the only video like it! Thank you
Video Like 👍 😊
Well explained
Yes. I was surprised that it was not mined or found.
Well explained on mercury
can silverish mercury turn red mercury ?
I’m just a normal dude (no scientist) but on the question of conductivity: I’ve seen mercury inside furnace thermostats and electrical switches over the years, so I’m assuming it’s electrically conductive, at least at low voltages. 🫡
Terrible audio - can't understand half of what is being said.
Thank you. I learned a lot
Thanks for your feedback Mark
@@crazycube001 sr i cn u help

Why do we know any of this. From single cell organisms to discovering and looking at single cell organisms
That's some process, who taught them? It's not something a person randomly figured out. What was the need for it forcing them to seek it?
hlw bro superb
Thanks a lot!!

Remember grade 6 Science Teacher putting Mercury on our hands to get a better understanding. 🤔🧐
It was probably gallium. Looks like mercury and is non toxic.
Mercurio me encanta
Amazing
Awesome
Soooo.... how did the people of ancient America mine and refine mercury?
i had a 30lb bottle of the stuff to play with as a kid my dad told me he got it of bearings at work
poor audio
What are you saying
There now finding ancient Mayan cites soils contaminated with mercury they think they used it for paints and other decorations I think they’ve even found liquid mercury in vessels it’s wild
Wow
👍
I always wondered.. if mercury is a metal, is there any possibility that we can make it have an electromagnetic property.
Kinda the Nail electromagnet experiment.😂
I have mercury in somalia 10 liters it has power
First of all, Ancients are not Hindus
that is why it is legal in our mouths
👏👏👏👏👏
💖
Making? I'd use a different word
Ancient hindus not, u say Ancient tamilans.....
ancient Indus Valley civilization people
They were not so-called hindus...
👍🌹👌🤝💐
thanks!!
is this recorded in a bathroom? haha
