Metal Refining & Recovery, Episode 24: Re-Refining Gold Using Bromine

[@NileRed]

Oh man, it was really cool seeing my glassware in your video!

[@liambay4636]

NileRed it’s cool to be in the KZbin science group

[@skateerdud]

You and cody should do a colab! I bet he could get better results in your lab and it would be cool seeing both of you working on this!

[@SiddharthJhakaas]

NileRed ah my favourite youtubers together 😍

[@diarya5573]

NileRed Colab!!

[@gentleman_shaco3879]

that's what i wanted to say that Wow he got nile red's glassware amazing

[@ACTlVISION]

This could've been confused as a NileRed video until you used a carton of frozen goat milk as a glorified ice cube lmao, never change man

[@sockmon1]

you are my new favourite reference-based youtube account.

[@diggymgee]

I love how accessible you make science look for people. It's like watching someone make furniture out of their garage or programming video games in their basement. It's the type of scientific media we need most to make the younger generation more interested in the sciences. Hopefully youtube stops dicking with your monetization.

[@sweetmeatnc1504]

Cheezits I totally agree, I always was slightly interested in science and chemistry in school, but never quite understood a lot of it. I've learned more from Cody on KZbin than litteraly every science course I've ever taken.

[@yaksher]

Honestly, more kids interested in Chemistry would probably be a bad thing... that shit's dangerous.

[@jackedup8790]

yaksher educate them. Not educating them is far more dangerous then chemistry

[@nickthethick7502]

Im A kid and i love school but cody is more engaging to me

[@davidmcgill1000]

Cody also apparently has far more cash than the average school does for science. Gotta love how he causally x-rays a roll of gold foil that he spent a few grand on with a device that probably cost just as much.

[@camelmer02]

Does anybody else love it when these chemist KZbin's refer to each other. Like Cody did with the NileRed flask.

[@micahphilson]

Yay, another precious metal refining video! I'd say I love this series so much, but that's also true of every other of Cody's series, so it's kind of redundant.

Hey Cody! I just started my first college chemistry course and I am loving it! I have been watching your videos for a while now and I really appreciate how you bring chemistry to youtube. You leave nothing out and make great videos! Thank you so much!

[@Nevir202]

Funny seeing comments like this, and knowing you've probably already graduated.

[@tile-maker4962]

"Bottle of frozen milk in the cooling water, keep it cold." Absolute mad man

[@mechadrake]

Goat milk

[@htomerif]

Why is your kwijibo telling us that gold is tungsten? -edit Since I made this comment without listening for an extra 30 seconds, I should probably explain why myself: After having read the manual, it has 3 relevant modes: Alloy, Alloy plus and Precious Metals. If you want to get an idea of what contaminants are in the sample, one of the alloy modes has to be used as the PM mode only tests for Ir, Pt, Au, Rh, and Pd. For those who are curious, Alloy mode measures Ti, V, Cr, Mn, Fe, Co, Ni, Cu, Zn, W, Hf, Ta, Re, Pb, Bi, Zr, Nb, Mo, Ag, Sn and Sb while the Alloy Plus mode adds Mg, Al, Si and P. You now know what I know.

[@-danR]

This explains nothing to me. All I still see is bad ROM code, and that that ROM should be swapped out with next-day service by a technician who flies in at the company's expense. Cody stated unequivocally that its not a hardware issue with the instrument.

[@htomerif]

Alright. You want more, I'll give you more. The gun works by x-ray fluorescence spectroscopy. It has several different x-ray beam energy settings (10, 20 and 40 keV or something like that). When you bombard an element with x-rays of a particular energy they re-emit photons ranging from the hundreds of eV to tens of keV (I think due to core electron ionization, as opposed to valence electron ionization). The mode you choose determines the x-ray energy and for some x-ray energies, the fluorescence of certain elements is indistinguishable from the fluorescence of others. This is the case for Alloy Mode. "Fix it in ROM" you say. "That r dum" you say. No, actually, the problem is deeper than that. Core electron ionizations tends to have relatively high half-lives before an electron from somewhere else drops into the missing electron slot, on the order of 10's of seconds. If you take a sample with the tube energy at 40keV and then switch to 10keV to get a different spectrum, the data will be contaminated by non-decayed core electron holes from the test at 40keV. In my original comment I wasn't sure which of these two explanations to give. This one is much harder to understand although it is more broadly useful. Also no one had told me "fix it in software" yet.

[@vertexrikers]

I did the same "not listening for 30 more seconds" but immediately paused and rushed for "Dude, wait, wot? Wolfram!? Y ain't dere no Aurum? Woot!" =D Thanks for the heads up m8. Sometimes the comment section really rocks!

[@htomerif]

vertex rikers: its interesting when you look for the manual for it, its easy to find but it says its not to be distributed or copied in any form. I'm don't think they quite get the concept of the "internet".

[@vertexrikers]

Well, many times such clauses, even tho 90% futile, are being added just to give the provider an edge in a hypothetic court case - like when someone creates a huge archive and redistributes without permission. Guess that clause ain't considered effective (regarding personal use cases) even by the provider =)

[@Lizardwarrior1]

That's the hardest earned $7.50 I've ever seen.

[@Hexalyse]

Yep, I was thinking he would make like $1-2k, but you spend hours and hours, plus the price of chemicals not taken into account.... not worth it if you try to make profit. But totally worth it for the science :D Thanks Cody for having the time and money to do this.

[@DamianReloaded]

You gotta add profit from youtube and it's probably very worth it. ^_^

[@mpk6664]

KZbin doesn't pay him, they don't like chemistry videos on their platform as it's "dangerous." Patreon is where he gets most of his money.

[@mpk6664]

KZbin has been cracking down on chemistry and shutting down channels.

[@Hexalyse]

Yes but I was talking for everybody that would like to try that to make a profit. Not anyone will get thousands of views. Plus I doubt his KZbin earnings from such videos are very high.

[@eternal8song]

I barely understand basic chemistry, but i love your videos so much. thank you for making them and educating all of us, Cody. If even an art student loves what you do, you're definitely doing something right.

[@Kitsudote]

Cody has the brain of a scientist but the heart of an artist :)

[@AtlasReburdened]

That still might not break into profit margins when you consider the time put in. We need more gold.

[@blakops000007]

Atlas WalkedAway Even then, the profit is never going to be that huge. But! You still need to remember, that the time spent is paid off through You Tube; perhaps even much more than the time's worth. So in the end Cody had made good profit; not much, but still, good profit.

[@blakops000007]

Plus gold is good investment; you never know when the economy is goning to shit in the future, the dollar collapses, or inflation hits sky high levels. Gold on the other hand,, retains its value throughout the ages.

[@AtlasReburdened]

black ops Gold retains its value until the very first time that it even remotely seems like we might have a viable plan to mine asteroids or other celestial objects. Call me a blue sky dreamer, but I'll stick to most of my reserve being food, weapons, equipment, and land.

[@AtlasReburdened]

Nate Yeah, I hadn't even thought about the reagents and the wattage. Suckage.

[@MilesFromExtraordinary]

If the economy goes that far south, few people will want gold. They will want food, water, gasoline, and medicine. You can't eat gold. No one will buy it when they're hungry.

[@brianartillery]

Bromine. What a lovely element. I used to work for a shipping company that used to import huge flasks (in 20 ft container frames) from Israel. They would be exported back home with some liquid Bromine 'ullage' in them. One of these flasks was damaged whilst stored in our yard, and a small amount of ullage escaped. It took the paint off the trailer it was on, several containers nearby, and ate several holes into the yard floor. It also meant half a day off for me, as HAZMAT teams quarantined our yard, so I came back from lunch unable to re-enter the office, and my boss told me to go home, as the ullage had 'wandered'. Lovely.

this is my favorite series on KZbin

[@roquri]

Was that an acetylene torch? If so, don't use that for gold. Oxy-propane is ok, but in a lab, we would not use acetylene, it contaminates the metal.

[@theCodyReeder]

What with carbon? The x-ray wont pick that up...

[@roquri]

Cody'sLab Honestly not sure. If we were fusing glass to gold, acetylene would total mess that up if the gold were melted and cast using acetylene.

[@aajjeee]

the fact that the xray wont pick it up is even more reason to not do it sonce you wont be able to quantify the contamination

[@samlolly6364]

thats probably beacuse you were trying to get the gold to react, or at least form some wierd alloy or mixture. pure gold is probably fine because is unreactive and carbon wont bond, the worst is geing that wierd crud on the surface.

[@lajoswinkler]

Industrial acetylene has phosphine in it, hence the smell. Maybe the crud comes from gold phosphide?

[@matthewbirdsey7231]

[@brianfaini]

Regarding that x-ray tool. Does the accuracy become affected by the environment? Like that gold was analyzed on the wooded table. Are the elements in the wood/finish being analyzed as well? How far does it penetrate? Im sure the output is adjustable. How is it working? What is the spread?

[@NotProFishing]

brian faini surface contamination can skew results but they beam only penetrates a few nanometers

[@theCodyReeder]

see this is why it needs another video. Put it this way a sheet of gold as thick as aluminium foil will block all the return x-rays while aluminium foil will block almost none. also since people keep asking the x-ray emission coming off carbon is so weak that even the air is enough to stop it.

[@iansykes6607]

[@RandomVideoGuy-qy8fu]

yeah he mentioned it a bit later on in the video

[@wgmoney96]

What happens when you comment without watching the video

[@theCodyReeder]

yeah, It is set up for detecting trace amounts of gold and so when I test something with a lot of it the software is like "wtf! ummm... oh I see must be tungsten!" I can fix this issue by sending it in and paying 1000$ for an update but its really pointless since I can look at the graph of energy returns myself and see that it is detecting gold.

[@-danR]

Mircea The explanation makes sense for a $2400 instrument. Not ~$24,000, or whatever it was. I'd want a software guy to come to my door in a Mercedes and swap out that ROM, stat.

[@imaghostbtw]

*PETAL CRAZED CABBAGE* you can filter it to get rid of impurities or distill it into its main components

[@adamkelly1320]

You could filter it to remove contaminants and particulates and I do believe there are machines that can take oxygen from the air and leave most of the other gases behind but I am not sure, air itself is a mixture so I don't know if you could refine it. Hope that helps.

[@EvelynH-tj1qt]

what do you even mean?

[@JaneAria]

I'm assuming by air you are referring to oxygen, the breathable part of air in which case yes. Talking about just air as the mix of gasses then also yes but nothing pure

[@cato2906]

Any gas is breathable as the word only defines a mechanical function of the lungs, you can breathe pure carbon monoxide just as mechanically efficient as you can breathe pure oxygen for a certain period of time, though it would not be advisable to try either.

Can you please extract lanthanum and/or cerium from lighter Flints? Like if you agree.

[@stephenkamenar]

thanks for the spreadsheet at the end. very nicely laid out!

Yo do me a solid and be my A Level chemistry tutor lmao

[@phatcat-st4gb]

I love how the software presents gold, a famously soft metal, with tungsten, which is one of the hardest metals in the periodic table

[@grassyclimer6853]

so youtube new i wanted to watch this it put it in my recommends on the side of another video. why not just notify me? I always watch cody play with gold or dredge a highway or dig a hole or just whatever.

[@MartinPlanner2]

you check the /subscriptions page at all?

[@MartinPlanner2]

that is weird...because of all the years and complaints of peeps i always land on the sub page and it shows everything, and if i missed something, i just look on the left side at the subbed channel names and they'll have a number of how many i missed from them...and i do get all 870channel vids on the sub page...

[@wildbill9863]

The only person ive ever known who was as mild mannered and chill as Cody seems to be would explode in fiery rage for a few days once a year lmfao

[@chrono0097]

95% Tungsten... Well...

[@Cypress_Stoned]

Super cool. Loving these chemistry vids.

[@Martin-zx5ip]

Doesn't dissolving gold and dropping it out with sodium metabisulfate give you 24 K gold. Also can you do a video on purifying paladium and silver.

[@theCodyReeder]

yes, unless you use too much, neutralize the acid, and drop out everything.

[@Martin-zx5ip]

What about the second part of the question :)

[@Quick_in_and_out]

What about saying thanks for taking the time to answer one of your questions?

[@Martin-zx5ip]

lol whoops

[@Martin-zx5ip]

thx for noticing

[@jpolowin0]

Very neat! Thank you for doing it, and showing us! If I were to make bromine, I think I'd use an ice bath on the receiving flask to minimize the amount of vapour. You commented on the warmth of the flask in which you reacted the gold and bromine... the stirrer itself generates more than a bit of heat. I wonder if it would be possible to reduce the AuBr3 electrochemically, perhaps with Cu in the other half of the cell as its anode. Maybe a bit of ammonium in the Cu-side solution to encourage the oxidation from Cu to Cu(II). It would be slower than reducing directly with SO_2 but you would probably get some nice gold crystals out of it. Au|HAuBr4||Cu(II)(NH3)4|Cu . Several times, you referred to "hyperchlorate", or at least that's what it sounded like. Should be "hypochlorite".
