Issuing correction on a graphic of ours, regarding Fritz Haber. He was not, under any circumstances, "bae".
BONUS QUESTION: In one part of the video we say we'd need to oxidize gold, in another part Dr. Farrell says he'd try reducing it. Any guesses why?
I believe electrolysis of seawater with gold anode is much more efficient than cynidation.
Is a metal-organic framework the same as ion-exchange resin?
Hi Reactions team! Love your videos! Just a small note.. in the subtitles, "femtomole" at about 3:50 is unfortunately transcribed as a drug name.. might be something you'd want to fix 😊
( update: This has been fixed! yay! )
I asked my kids what "bae" was. And while Haber was a strange, complex and contradictory figure, I definitely agree that he was not "bae".
If you're going to ask us guess, then you probably should provide the answer as well. Isn't that right?
There are proposals for extracting it from brine leftover from desalination, it's a lot more concentrated and it's basically free (they'd probably pay you to take it off their hands)
And if we develop small modular reactors and/or fusion, desalination would be a piece of cake! You'd get fresh water, salt, and gold!
Use pouring with bacteria ...from honey.after proses avogadro system acid or natrium hydroxide
Right. Rest of discussion? Maybe solar powered?
Unless you are taking dump trucks of salt away they aren't going to pay anyone to take it.
You also will have a substantial quantity of non food grade salt to get rid off once the gold has gone only viable as road grit.
Whatever happened to old school refining? You heat it up. Gold is nearly indestructible unlike other metals!
These videos are such well-produced and made, underrated!!
"The secret ingredient is lies" lmao
Gold would become worthless then if supply increases that much
@@faenethlorhalien Usefulness can generate demand but if there is an overwhelming supply, then it does not matter. Once you have supplied enough gold such that all demand is satisfied, anything more than that becomes valueless (not factoring in the prediction of future trends). You cannot easily generate demand the same way you can generate supply. So I would argue its rarity (abundance) has more of an effect than its usefulness (value). And without market manipulation, I doubt that gold would retain much of any value if that amount of gold was suddenly added to the market. (Purely speculation)
@@ravenous9577 Gold is a very useful conductor in electronics, making gold recovery one of the primary targets when such items are recycled. As it stands, metals with much less favorable qualities are used when gold prices make it too costly. As such, it would take a truly massive amount of cheap gold added to the market before its value for industrial applications cratered. The other metals used in its stead would suffer price declines first. OTOH, alternate users of the same metals would benefit from the reduction their material costs.
Investors whose fortunes hinge on those price remaining stable would be adversely affected but the world in general would be better off as technologies become accessible to lower income regions.
Manav zavari, you are correct.
If the availability of Gold is very high, the value of Gold will go down.
The global economy will affect negatively.
Because, Global Financial stability is based on Gold.
I think, already some countries have been doing it.
Because, it is far cheaper, than operating Space Exploration.
Anyway, it is 100% true, that the sea water contain Gold in pure form and exist as molecules with some elements, as well.
I love the vids - but despise the graphics and audio choices made for fritz haber, the father of chemical warfare.
yes, we got a little carried away thinking about nitrogen fixation, as I'm sure most people often do. Please see our pinned comment for our retraction.
So if we sort out fusion energy production and subsequently have limitless energy this will totally be viable...
Future Energy Plasm cold Fusion technology....
You know at this point you'd probably make more money selling the salt you evaporated from. By my calculations, you can get $1 by selling the salt from 700mL of seawater, instead of the gold from 2 GL of seawater.
we are in the salt mining business. on the side sometimes we sell gold.
Why not clean the sea water for use on land and get all the minerals as a by product?
Learned about this channel through the survey. Good stuff! Looking forward to the next video.
Make a device like a big box that traps micro particles of gold, at the bottom of the sea (assume gold will be more at the bottom) from seawater that pass through the device. A special filter with active carbon might do to adsorp small gold particles onto it. A gauage to measure how many gals of seawater had pass through the device. Hehe
I think the trick is doing something like desalinization, which has some inherent value on its own. A byproduct of most desalinization methods does produce gold and can offset some of the cost but still isn’t cost effective. A question I have is, one of the largest gold mines on earth is in South America and mines microscopic gold from the coral reef. Does the coral get that gold from the ocean and if so what process does it use to concentrate the gold? If not, where is the gold coming from and why is the coral storing gold?
Probably a mechanical process where it settles down
Inspired by this video, I ran an actual calculation for a novel project: A large ship with a 5 meter by 5 meter composite containing a known metal-organic framework (Fe-BTC/PpPDA) with a high selectivity for gold (but not for copper or nickel) passively collecting gold while sailing between Sweden and the United States. Results: Still not encouraging! The basic premise: A 100 kg MOF composite would cost somewhere between $5,000 and $20,000, but would trap gold weighing nearly 100 kg (worth $5.6 million)! The unsolved problem: How to expose this MOF composite to 10 to the power 17 liters of sea water in order to obtain 100 kg of gold from it? For simplicity and for the sake of calculation, assume that your ship is sailing through a cuboid of sea water (Sweden to US = 7,700 km; width = 5 m; and height = 5 m) and that the MOF composite is exposed to the entire volume of sea water contained in the cuboid.
Horrible idea. The carbon footprint and ecological destruction would be ENORMOUS. Just to satisfy human greed.
Allahu Akbar best ide to take aau etc❤
Bismillah to be Alhamdulillah...Allahu Akbar cold fision, ..transmutation p😊😊❤❤❤🎉🎉🎉oklasma
I know how to do it, but I would never tell it publically. There is a reason biblically a third of the ocean dies. Why accelerate the issue.
I have a question for you,can you tell me at what precise level in the salt sea water that the Au. atom floats at? I know the answer,and this knowledge is extremely valuable.
Fascinating video, almost as fascinating as the number of times your hair color changed!
Things to take into considiration are the location of the seawater being processed since seawater closer to volcanic activity or known sedementation for gold deposits etc can contain much higher concentrations of gold p/l .
Water desalination plants remove brine from sea water, try reactions with that.
Incorrect, 20 mil tons are on the ocean floor, NOT in the water. Only a tiny fraction of this gold is in sea water. Sea water is 0.01-0.03 ppt gold, but going with your number from 1990 of 1 gram in 100 mil tons of water (aka 0.01 ppt), the cubic mile (4 bill tons) of sea water behind you would only contain 40 grams which at the time of your video was only $2,300 ... NOT $1 million, lol. That's because 99.94% (according to these numbers) has sunk to the ocean floor already.
With the rise in oceans and the need for fresh water bigger and better desalinization plants will be needed. The big problem now is what to do with the brine. I would guess some of our new scientists will figure out how to extract all the minerals and various elements from this brine including lithium for their batteries.
I like to call it "The invisible road of gold" in our oceans.
Hi there, Im doing experiments extracting preciious from river flow, put 100g of coconut carcoal into cloth bag, negative titanium electrode placed inside charcoal, made a solar panel generating 1,5-3v depending on sun activity, (to attract mostly precious, silver-gold-rodium-platinum-iridium-palladium, such voltage range ) and positive electrode made from a piece of iron, placed both electrodes into river, first plus to beginning of waterflow than minus, distance about 2 meters, tried also to solt water placing in that area a bottle with salt, for better electric conductivity, but better results got without salt. After 40 days of work took charcoal off, heated to wet condition and got a weight of approximately 120g!!! Looked at microscope and saw in it some small places of YELLOW on a charcoal surface! But mostly covered with some white metall. Now have a couple of charcoal portions from different experiments and thinking about extraction from charcoal, will try to make a charcoal powder than grab it with heated lead and use melting furnace and cupelation to extract from lead.
Quick scan of comments, nobody mentions Cody's Lab. Hmm.
WOW!! At first I thought she was delusional then turns out she's a genius. I'm glad I kept watching the video.
Hows the weather up there
As I said you don't need a college degree to extract Au from salt sea water all you need is the simple extraction process knowledge then apply it.
Genetic engineered algae may be the only solution.
Well that's a bummer. Maybe we ought to just fly out to space, capture a Comet and harvest the gold from it. We'll all be rich! At least I learned something new today so thank you for that and that lesson is worth its weight in gold. (See what I did there? )
What about the following? Using wave action to firstly pre filter the seawater and then pump it through a reverse osmosis filter designed to filter out molecules the same size as the gold in solution (say AuCl3 or NaAuCl4 etc) the only cost will be the equipment and maintenance. If properly designed, the pumping action can even be used to generate some power after filtration (no, I haven't done the math). All you need to do from there is process the concentrated salts.
Serious question. Your process required boiling seawater to extract the salts. What held you back was the billions of gallons of seawater you would have to process.
Nature already did that for you.
When an ocean evaporates. All that is left are the salts.
The world mines millions of tons of salt every year.
Question how much gold is in a ton of salt? Is there an economical way to extract gold from salt?
I know the extraction process of Au. From salt sea water and its extremely feasible and a laymen can do it quite simply.
Hi thanks for this subgect i want to tell you you can make test to extract gold from sea salt befor filter it i mean just fresh sea salt
Great idea. Does my store-bought sea salt have gold in it? It's economic arbitrage time!
I'll be interested to see how this process gets developed when we are no longer on the planet. Eventually there won't be any more mine-able gold on Earth and then the question will be where will we get it from? Recycled electronics or maybe asteroid mining? Both also seem quite farfetched and expensive. But at what point will it be worth the cost to obtain the most precious metals?
Interesting video as always.
Electronic waste is by far the best of those three options. From an energy standpoint, asteroid mining is probably more feasible than seawater mining.
In what form the gold is in the sea water?
Anode matrix extraction is the way to go.
I wonder if this would be more cost effective if the salt that was left over from desalination, such as from more traditional techniques used in the middle-east like ~boiling, could be processed. About 3.5% of ocean water is salt, so 3.5% of 2 billion liters of water is 70,000 cubic meters. Still a lot to process, but if the salt is already there in the form of waste it is one step closer to a gold rush.
The Bazigar Music at 2:23.. Baazigar o Baazigar..
Why you dont talk about lithium or uranium in sea water
Agggh! VOCAL FRY!!!!
Bae-ber...Nice
You are not going to get this out of cupfuls of sea water. I already tried that. I doesn't work. But I have alot of Ideas I have not tried yet
There is another way of doing it that would be easier but I won't have my information with me. The Germans did it before World war 2 and they were sucessful. Were do you think the Germains got all that gold?
Hah jokes on u I only need alittle gold for a lot of gold atoms. ⚛️
Ok researchers....
The U.S. government knows how to do it but not feasibly. So they say!
Extracting Au from sea water requires the knowledge of what level the Au. atom floats in the water. I know that level do you?
Hello. I am working on a project to extract gold from the seas in Turkey. A method that has never been tried before. I don't know if I will be successful.

@ahmetonder7750 Your success depends on your precise knowledge! I'm presently working on the same project and almost ready to get on the water and exercise my extraction process, this is my present goal. It's a financial goal to help myself and to help Illinoise homeless people in which iam one of them. In order to do it correctly you will need metals to extract the Au.atoms from the bodies of salt water. I'll keep you updated since very few men on planet Earth possess this extremely valuable knowledge. I too must try it,since I claim to possess it.
@ahmetonder7750 Your success also depends on precise knowledge and if you know the exact location and depth of the Au. atoms you will be very successful in a very short period of time. If you have any questions I will answer you but I will not give you the exact location of the invisible road of gold beneath the surface of sea untill I try it myself. I have to prove to myself that my facts are absolutely true and correct.
@ahmetonder7750 You must know that you will be successful before you even try. For example,we know that there is trillions of dollars worth of Au. #79 in the saltwater seas,You must know the simple extraction process and the exact location of the Au atoms were they are greatly condensed and if you do now all you have to do is try it and go fishing.
Op
My U.S. scientists have informed me that there is 25 tons of Au. in one cubic square mile of sea water.
bismillah Allah SWT ridho to be this project..aamiin Focus to take all rich minerals rare earth and so much goon to try best takin Au,PD,PT fe ,th etc....pgm or green gold.yes this is true
Let me make gold by tricking you into watching this. At least show something, this was a waste of my time. How are you going to re give me that back you cant! Waste of time.
totally ridiculous
Iam not expert but all costs in video are hypothetical cause what if we dig a hole and dam under sea level and use sun energy for boil water and create electricity whit vapor cost are to 0$ and you sell electricity for treatment of salt in gold and other metal
