#silverplating - แนวปฏิบัติและการใช้ชีวิต
I worked as a chemical engineer for a precious metals reclaim company and developed my own process for precipitating silver from silver nitrate, which is the waste product after dissolving gold in aqua regia, nitric and sulphuric acid. It is terrifying to watch these men, with no protective gear, no respirators, some barefoot, handling dangerous chemicals and 2,500 degree crucibles. The red fumes from the nitric acid are especially toxic, and I had to engineer a fume scrubbing and neutralization system. I admire their effort, but am shocked to see such dangerous working conditions. I know.
I’m not shocked this has been a long standing trend. Scrap gets sent to these undeveloped countries to recover these precious metals. You should see the videos of the ship breaking yards in India. I feel for these people but never surprised about what they go through.
Hello john? I have query to u , if u reply , it'll be helpful for me , please reply asap
You can hear them coughing in the background. RIP
This is complete madness they will all die soon
but imagine how soft their hands are.
So for 500 grams of silver worth about 350$ everyone on that video had a healthy dose of nitrous oxide and a splash of nitric and hydrochloric acid. Excellent. I'm disappointed they didn't use hydrozine on top of that.
That would have been fun to watch. Nothing like a little hydrazine to clear a building....or an entire base.
I think I'll just buy my damned silver.
@@ananda_miaoyin Your silver jewelry probably comes from there, but not much chance you'll give up your shiny objects.
c@@oldschool1993 I gave up all of my "shiny objects" to the Caldor Fire of 2021 so....thanks.
@@ananda_miaoyin Well you can thank the tree huggers who have stopped any preventative logging or brush clearing for decades and creating an environment more explosive than a fireworks factory.
plenty of replacement people so don't worry chum.
For the curious the big items are microwave duplexers for the older cell phone systems. Each compartment is like a little bell that rings at a particular microwave frequency. There is a series of these bells tuned to each receive and transmit frequency. With a sequence of these they can connect both the transmitter and receiver to the same antenna and still have a separation factor of a million million!!!!! The latest cell phone systems use much higher frequencies and need much smaller bells but just as many.
Thankyou
👍
Muito legal..mas eram feitos de prata?
Thanks! I was going to ask what they were.
I guessed right ! 😂
The safety of this operation is on another level. ;)
I did a lot of squinting with a head turn so I didn't get splashed.
On a level that I don't want to be on
The safety level is over 9000...
I was just going to say... makes you really appreciate not having to work in a sweatshop in a 3rd world country.
i guess no Surprise O.S.H.A visits..
That one slicked back guy is wearing sandals while creating aqua regia. Can we all take a moment to admire his commitment?
Can you hear them coughing after being exposed to the acid and nitrogen dioxide fumes? Watching these workers be exploited like this is depressing as hell
Yes
Same. 😳
That’s a third world shit hole for you. Be thankful you’re a privileged individual
Third world country,
third world intelligence..
The orange gas that was produced was chlorine gas and nitric oxide that auto-oxidizes to nitrogen dioxide, these people probably wont live past 35 if they're lucky
Respect to all these men risking grave injury and health problems just to feed their families
Brave? Who said they have families?
I cant possibly respect this idiocy.
8:54 I lost my shit, when he regulated the forge blower with the piece of paper. That was some next fucking level shit.
I wasn't sure I was seeing what I thought I saw but you confirmed it, I thought it was going to be a big mistake if it got sucked into the impeller ! 😳
@@flipflopsguy8868 there is probably a mesh there
So you use the F word to make you appear cool?
You're a troglodyte.
A danger to handle these chemicals without a mask and safety clothing, these men will be short-lived
Very short. Respiratory failure

Sadly but true. Very short

But still longer than starving to death. So on the balance....
I wonder what river all these chemicals end up in. I suppose it makes fishing easier when they’re all belly-up.

They water their crops with it too! And make baby formula!
That’s adorable
@@colonialcharlie8702 Where it gets HIGHLY diluted before going to a water treatment facility...
@桜 ᴹᵘᵏᵘ⁴² 👽 I could put in a well if I ever needed to.
In my work I deal in dynamic risk assessments every day. I find this to be deeply disturbing on many levels. These men will not live beyond 40 years old. And if they do it is sheer luck...!
You are absolutely right. The tragedy of our country.
Those acids are mostly toxic and I don't want to imagine what's being done to their lungs. I am in awe of what they are doing to keep themselves and their families alive.'
They will live beyond 40
@@peacewithoutbias6692 Like I said...sheer luck...
@@hanksCorner7011 They do this because of poverty it's nothing to be in awe of
I believe SREETIPS would need to have a chat about safety here
Love all the protect they uses, gloves, eye glasses, masks, ect. men without finger prints or lungs
and Sandals
*etc not ect.
Anybody else see dude sitting in the chair looking at his phone while them other three guys were on the floor working and breathing that acid?
Wonder who's making all the money 🤭
This is the bitter reality of this world.
Hes probably like lower management lol.
@@ManVSMachineHD could be, but it doesn’t mean, they have to work in a dump yard!
Everything is dirty and filthy!
Nobody cares about a little Organisation, they throw stuff around and hoarding piles of Aluminium, instead to stack it, and get more place.
You don't know what he's doing... he could be searching ads for more scrap to process, finding a precious metals merchant who will pay the best price, making sure the workers aren't pilfering. Management is part of the cog. He could of started off at the bottom like the workers, worked hard, saved and invested in equipment, and created a business that now employs other people.
Point taken I already spotted this dude on his phone commented prior to reading your comment sorry.
The risks a man will take to feed his family. Brave men indeed.
They have no idea about risks... these idiots have no idea what they are touching or inhaling. So stop trying to make out like some inbred cave apes are brave or courageous!
Call it that
And all this chemical waste in the sever.... true hero!
Not really brave, but ignorant of the hazards he is exposing himself to.
Actually it's all bad upbringing, generations of it, due to harm and no focus on doing no harm or even trying to understand what harm entails and why it should or must be avoided. Agreed? Know better about what the fundamental core problem is?
I'm amazed their commitment to safety, a guy was actually wearing gloves.. Well, A GLOVE...
apart from the safety issues...they actually melt the silver chloride in that crucible together with soda. this way they will always loose some silver because of the bubbling of CO2 that can be observed upon adding soda and also due the fact that silver chloride itself boils at high temperatures.
better to wash the silver chloride with hot water to remove potential lead , then treat it with hot sodium hydroxide aqueous solution to convert it to silver oxide. wash, dry and then load the silver oxide into the crucible for melting.
exactly... these guys need to watch some Sreetips and apply what they learn. (insert any other competent TH-cam chemist here)
The really sad part was when they were pouring the sulfuric+nitric+more batch into the big tank; and kept breathing those lovely fumes. Wow, could they not put it on a platform, use a hose and allow it to take a minute to pour in (while they watch from a distance)? Is getting a tall table (which would increase worker safety 100 fold) really that hard?
@@chouseification You are talking about people who wipe their asses with their hands.
They did wash it atleast once.
do you think they really give a shit? tehyre working for probably 5 dollars an hr in unsafe condition be happy they do anything.
I spent my working life in Chemical works, this video is truly terrifying on so many counts. No PPE, mixing acids, pouring water into acid should always make the water stronger not the acid weaker, exposure to NOx etc.
These men should not have to work in such dangerous conditions, easy for me to say coming from a wealthy country, but they probably have little choice, they take the risks to feed their family.
what about the guy filming for ad revenue, hard lives all around.
kind of makes you hthink we dont have it so bad over here in the "west" does it? this is why i dont complain about things that many otehrs do..we might think we have it bad but other people have it much worse. maybe soem peopel whining about covid should watch this video..or soemone who whines about making 20 dollars an hr to work in an air condtioned building maybe show them this video..these guys probably do this for the equivelent of 3-5 americna dollars na hr..probably less...look at their safety gear? sandals and robes..
You know I watch a lot of these videos from you and all of them are absolutely fascinating I just have one question how many toes do you guys lose a day!!!
thats irony at its worst, these guys are not the pampered lot from west, and they know what they do.
Although i am so much disappointed on their treatment of extremely hazardous acid fumes,and feel so sorry for them...
They can only lose 10.
I notice the bloke at about 4.00 actually was wearing gloves. Hope he didn't get mocked by his colleagues.
Nah, its ok, it only one glove.
Чуваки просто бессмертные........

These people will not get old.. ;-((
good die young eh
Has anybody in this village presently lived longer than their forefathers? I have to believe they’re lifespan has shortened since this process has begun.

The more of these videos that are put up it really shows what deep manure the world is really in.!!!!!!!❌❌❌
It's just the third world. Explosive birth rates plus low median IQ do this.
There is nothing „amazing“. This type of HF electronics is very rare and the missing personal protection of these employees will shorten their life expectancy drastically….

They will be visiting a nephrologist very soon with acute renal problems. I've seen this very often with people that spray poison in corn fields here in my country, none of them reached the age of 40.
Earth is overpopulated indeed, so some people have to die
how much chemicals do you go through per day
Enjoyed your video but hated seeing people working around stuff that's toxic without safety equipment
I don't know why these people don't care about safety
@@ManVSMachineHD Because they don't know maybe? But oneshot is so right....this is so dangerous........these guys will not be to old i am afraid...
@@thinge27 You are absolutely right
Maybe it's a case of do the job or starve.....
Care?
Or perhaps don't have the same understanding or even the same privileges that some do.
Think about it.
Those look like the resonant cavity from some antenna waveguide. Neat.
Duplexers and combines mostly for GSM. Dcs, 3g systems. Probably stolen
Mobile phone base stations. Kaiser power electronics on youtube did a series of teardown and explanation videos. Like most microwave engineering, it's basically one level away from black magic.
These are older generation 2g and 3g cellphone microwave duplexers. Pakistan is now mostly on 4G Cellphone network, so older network equipment is being wisely recycled, and No these are not stolen. In western countries they probably throw them in landfills.
@@redfordrn Western countries still use 2g, 3g, 4g what makes you think they throw them away. I also see something other than duplexers on the piles there.
@@leosedf not in my part of the US, my 3g phone wont work anymore
Well done!
Excelente medidas de seguridad
I don’t like that orange fumes coming out of those plastic drums 😂
Pure poison and they even not wearing respirator mask
Nitric oxide highly toxic
Are those the new Red Wing work sandals I've been hearing about?
Handling strong acids with zero PPE. Brave
Stupidity
Long process pays off💪🏽
Max 250e
Where do they dump the polluted liquids?
The next river or in the nature 😢😢
Shame on you... they wouldn't dump it... they sell it to the kids in the next village for their recycling efforts...🤨🤔😐😎
Kind of the same way thieves are getting precious metals out of your catalytic converter‘s
These men are so brave, doing their job perfectly fine despite the toxic working conditions and acid burns. Kudos!
back in March 2022, 700 Euros for 1kg of Silver. They have $350 Euros. Each person gets paid $10, the water full of acid and chemicals is thrown in the river, new scrap is bought, and they have a profit of $200 every few hours for the boss.
love the health and safety
Glad he's got safety sandals on, so if the acid splashes, he won't get any on his feet.
😂😂😂
Just his toes, its fine
@@A6Legit I guess since he has 10 of them, he can afford to lose a few...
Wow. What an amazing technique 😲....
Amazes me they aren't dead yet.
3 died last week but quickly replaced by 3 more....
What are the melting put things made of, how come they dont melt and how are they made???
Just awesome

Smells just like moms cooking
Dang just imagine all the stuff in the landfills or in the ocean that has silver in it!
After WWI or WWII , dont remember, was the idea of paying the debts with silver gathered from the sea. it got srapped becasue its way too expensive. Same here, if the workers would be payed fair and saftly would be demanded, the cost to gahter that silver would get too high.
@@antonsmith1497 Basics such as gloves and shoes would go a long way to helping. It doesn't have to be to EU standards to make a big difference.
@@artytomparis And filther masks that cost more than those people earn per month.
I enjoyed the video and hope you enjoy the rest of your life with like two or three years of lungs pain.
I am glad they are all about safety!
Why not refine it with lye and sugar? Then if you ultra fine, do silver crystallization.
Класно когда у людей есть запасные органы. Хотя и не обязательно.

That was interesting to watch. In the beginning, you can tell who the boss was and who were the workers.
The only guy with a chair is just browsing his mobile... clearly, the boss.
Hahahha.. yes
People doing what they have to to survive.
This should make all you over entitled people realize there's a cost for your cell phones and electric cars in the end.
People who have time to cry about their “rights” or race or gender problems should be made to watch how these people live.
And you, too, with your computer, right?
What are you using to post this comment? A carrier pigeon? Hypocrite much?
This isn’t the cost of the cell phone or electric cars, this is pure metal reclamation. It can be done safety and new equipment isn’t dependent on this particular work.
Trabalho escravo sem nenhuma segurança, infelizmente estes trabalhadores terão um fim de vida precoce e doloroso,. muito triste.

Оставшаяся медь стоит дороже смытого серебра, так что что ещё стоит откидывать к стене!
То, что вы считаете медью, на самом деле не медь, а алюминий.
Да, такой объем фрезерованного металла... Сколько однако труда потрачено... Хотя если посмотреть на добычу, там другая крайность, там тонны камней перетирают в песок и пыль... Чтоб выделить эти крохи...
Glad to see all the safety measures taken. Does anyone have any nose hair left?
Ребята, возможно для вас это будет звучать неожиданно, но азотка почти не растворяет алюминий. Для чего использовать меланж, если можно просто азоткой смыть, для того чтобы сохранить медный подслой? Так его там мизер в сравнении с затратами на серку.

They probably dump it in a river / sewer
I’m wondering if any of these men are still alive. Wow!
4 of them died this week. They were Mohamed Khan, Mohamed Akram, Mohamed Asif and Jonathon Allen.

I do some precious metals recovery as a hobby and this is just WILD!
R.I.P.
Ladies and gentlemen, this is how all of the precious metals for your 'pollution free' electric cars are recovered. As long as it's not happening here in the good ol' USA, everything is great. 'Green energy' all the way! Oil bad.
Nothing to do with cars
Scrap life, sounds like you have an agenda, and little understanding of the wider picture.
@@bushratbeachbum what, exactly is the wider picture?
yep, we are just moving the pollution to diffrent palace now. not enough metals to electrify transport on this planet.
This is very environm friendly, compared to the lithium production. This whole electric car thing is a big joke
They could make more sorting those screws and selling them on Amazon.
The mouth of the screw gets damaged due to the opening with the drill machine. This is why he only sells in scrap.
