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 The latest cell phone systems use much higher frequencies and need much smaller bells but just as many.

The safety of this operation is on another level. ;)

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.

That one slicked back guy is wearing sandals while creating aqua regia. Can we all take a moment to admire his commitment?

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.

Respect to all these men risking grave injury and health problems just to feed their families

[rafaelpinheiro]

A danger to handle these chemicals without a mask and safety clothing, these men will be short-lived

[farpointstation]

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

[GruntUSMC]

Love all the protect they uses, gloves, eye glasses, masks, ect. men without finger prints or lungs

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.

8:54 I lost my shit, when he regulated the forge blower with the piece of paper. That was some next fucking level shit.

[yanhasmut]

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!!!

[TheTorkerman]

The risks a man will take to feed his family. Brave men indeed.

[truthjunkie]

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...!

[FarazBeg]

I'm amazed their commitment to safety, a guy was actually wearing gloves.. Well, A GLOVE...

[visionofwellboyofficial]

These men are so brave, doing their job perfectly fine despite the toxic working conditions and acid burns. Kudos!

[johndoyle]

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.

The more of these videos that are put up it really shows what deep manure the world is really

[evileyemcgaming]

how much chemicals do you go through per day

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.
