“A dream. It’s perfect”: Helium discovery in northern Minnesota may be biggest ever in North America::For a century, the U.S. Government-owned the largest helium reserve in the country, but the biggest exporters now are in Russia, Qatar and Tanzania. With this new discovery, Minnesota could be joining that list.

This is the best summary I could come up with:


MINNEAPOLIS — Scientists and researchers are celebrating what they call a “dream” discovery after an exploratory drill confirmed a high concentration of helium buried deep in Minnesota’s Iron Range.

Prior to arriving in Minnesota, Abraham-James was working in Tanzania, where another helium discovery was made, but at half the concentration as found in the Iron Range.

The inert gas is likely known by most consumers for filling balloons and blimps, but it’s actually one of the most sought-after commodities in the world because of its versatility; as a liquid, helium is among the most effective and safest coolants around.

Dr. Grant Larson, a radiologist at Hennepin Healthcare, said the health system’s four MRI machines rely on helium to operate.

“We’re aware that it could potentially render us vulnerable to not being able to provide access to our patients,” Dr. Larson told CBS News Minnesota.

“It’s not just about drilling one hole, but now proving up the geological models, being able to get some really good data that wasn’t captured in the original discovery,” he explained.

I don’t disagree with your general point. But finding a new source of Helium, regardless of the rate of use, is a good thing.

That aside – are you saying Helium is related to climate change? Curious to know how, if so.

stembolts@programming.dev on 02 Mar 2024 16:04 collapse

Edit : minor addition. I was reading a comment the other day and found out helium can also result from other reactions outside of a star, such as the decay of a radioactive element, which ejects an alpha particle (which is just a helium molecule with special attributes, aka no electrons). The alpha particle crashes into something, picks up electrons and suddenly its a helium.

No, they are clearly making the following comparison.

  1. For climate change : World is heating up, heading toward the result of mass extinctions. The most valuable resource is the time to act. Ten extra years to work on the root cause. Unsustainable emissions.

  2. For Helium : A finite resource is being exhausted, heading toward a world with no helium (helium is typically created by one of the fusion cycles in the core of a star, fusion is a nascient technology on earth). The most valuable resource is time to act, +X% helium extra supply to address the root cause, unsustainable consumption.

In both cases, the root cause is being (mostly) ignored.

So they’re pointing out that if you have 800 finite helium, then suddenly you find out you have 880 helium… that hasn’t changed the finite nature of the helium. The root cause remains a “spending problem”. And they are likely annoyed that 880 ~> 880 results in, " Omg yay!" vs what should be, “Oh thank goodness, more time to address the root cause of consumption.”

Idk, was that not obvious? I’m not being facetious here, I’m really asking. Brings to mind the “curse of knowledge” fallacy where when you understand something you assume others do, and they often don’t, resulting in disjointed communication where the listener can’t grasp the idea. As condescending as this sounds I assure you its only because I’m not a writer, I’m legitimately making an attempt to communicate neutrally with you as we both seem to have genuine interest.

Anyway, corrections and such always welcome. All numbers in this post made up for illustrative purposes only.

That argument makes sense, it’s hard to view finding new helium deposits as good news if we keep wasting helium.

" But see, we’ve got a little problem".

The men, grizzled helium miners all, look concerned but defiant. These rugged hardworking may ultimately be under this man’s purview, but they’ll never respect soft hands with manicured nails that have never felt thing ring of the pickaxe against a brand new helium de}osit deep in mother earth.

The men look around nervously, as if a{using looking at Joel on purpose. This is a trepidation the executive does not share as,. Motioning to security guards he walks towards Joel.

He holds an empty hand up as if holding something, displaying it before the miners.

Tommy’s dad didn’t steal tank of 6N helium, but it did rolled off the same facility using the same process, main impurity being air (considering it’s a rather minor use, maybe balloon gas is just what is left after cleaning or purging empty helium tanks of higher grade. so it’s maybe not a massive loss. recycling helium within cryogenics and MRI would provide more benefit)

also wtf is “grade”, 6N means “six nines” means 99.9999%. (americans will use anything but metric units) liquid helium freezes everything else out so it’s 5N without any special extra purification, or at least that’s my impression from looking up spec sheets of helium from facility that i know uses cryogenic purification for it

Signtist@lemm.ee on 02 Mar 2024 16:58 collapse

I don’t know much about Helium, so I’m a bit confused… What’s to stop us from purifying grade 4 further into 4.7 and beyond besides cost? If the only thing stopping us is cost, then it’s not inaccurate to say that, regardless of grade, the non-renewable element of Helium is being used in frivolous ways because it makes more money to find profitable ways to use the lower-grade helium than to actually further purify and conserve it for more important usage.

Anyolduser@lemmynsfw.com on 02 Mar 2024 18:16 collapse

So the cost aspect is absolutely massive. You can theoretically filter elemental gold out of sea water, but it’s not reasonable to do that to supply gold for use in electronics. Similarly you can purify helium as much as you want but at a certain point the cost makes whatever you were doing with it prohibitively expensive.

Right now we’re still pulling helium out of the ground alongside natural gas deposits. We’re also not doing everything we can to recover, recycle, or substitute the industrial and scientific grade stuff either.

As less helium gets extracted the cost will go up. This will put market pressure on all users to use it more efficiently or find substitutes wherever possible. If the price goes high enough it might also drive producers to purify helium that might have been sold at a lower grade in the past.

This find in Minnesota pushes that future scenario down the road a bit, which can either extend the status quo or buy time for technological improvements to be made that will make use and extraction more efficient.

Donjuanme@lemmy.world on 03 Mar 2024 10:06 collapse

yeah it’s distilled off from nitrogen-heavy natural gas, like you could do with nitrogen-heavy gas without helium, or even air. all three processes are done commercially. the issue is that helium bearing natural gas is limited in supply and getting low enough temperature at latter stages of helium refining and liquefying requires bespoke facility. this part is hard

No helium found on earth ever, was pure enough for cryo. Not even close. All helium is found in low concentrations and spun extracted to concentrate and start to purify it. Then there are additional filter methods to finish concentrating it. Removing the hydrogen is about the hardest because it’s also abundant and small and light.

But helium used in balloons can absolutely be concentrated and purified.

skillissuer@discuss.tchncs.de on 02 Mar 2024 14:49 collapse

it’s much more complicated than that, and the most useful property of helium is its low boiling point. it goes like this:

first, you start with natural gas that has some nitrogen, some water, some helium, some carbon dioxide, heavier hydrocarbons, thiols, dust, and such. mechanical filtering gets rid of dust and mist, water, carbon dioxide and thiols are removed chemically, heavier hydrocarbons are removed on active carbon. now we have mix of methane, ethane, hydrogen, helium, nitrogen, traces of carbon monoxide, dioxide and water. this all is cooled down, first just to freeze out these trace amounts of water and carbon dioxide, then to liquefy what is left.

next this liquid mixture is put through massive distillation tower, allowing for separation of mainly nitrogen and methane. this nitrogen and methane are end products, some are sold as liquids but most are regasified in order to cool down incoming gas and save some energy. another product is helium concentrate, at this point it can be 50% to 80% with rest being nitrogen but this depends on exact facility.

then, some extra air is added to helium concentrate, it’s heated up and passed over catalyst bed. this is done in order to burn out hydrogen and any hydrocarbons, because separating oxygen from helium is much easier than separating hydrogen from helium. products of this burn are water and carbon dioxide that can be separated chemically. then again it’s all cooled down, nitrogen and oxygen are liquefied, then it’s all cooled down further and from some 30K on it’s just helium being circulated as gas because you can’t liquefy it like any other gases, it needs a special process. on every pass, with extensive recycling of heat some part of it is liquified and this is the final output, 5N liquid helium.

at least that’s how it works in a facility built in 70s in then eastern block. now it supplies half of europe and a research facility situated nearby. i suspect it was built with at least some military applications in mind during this time, namely helium is used for pressurizing hydrogen tanks of rockets, but also soviets toyed with an idea of using gas lasers militarily. this requires a supply of helium, and a supply of neon is also a nice thing to have in this situation. neon was produced in Azovstal cryogenic oxygen factory serving nearby steelworks, as it can be separated from air. it ended up providing virtually all neon for semiconductor manufacturing in the world, but from what i understand there are alternative suppliers by now

skillissuer@discuss.tchncs.de on 02 Mar 2024 15:27 collapse

it’s pretty fucking hard. only six countries in the world produce helium, and you get engineering challenges that don’t exist anywhere else. for example you can’t use any grease on helium turbine bearings in the lower temperature stages because all of them freeze, so the solution is to use gas lubricated bearings. this is some serious precision engineering that has to work in extreme conditions

it’s also hard because the simpler way of liquefying gases, like the one used for nitrogen that uses no moving parts in the coldest part, fails for helium, this makes liquefying helium harder than any other gas. it’s also hard because of limited availability. it’s hard because of massive capital costs and lots of custom machinery. it’s hard because of scale required. about any other compound can be manufactured without at least some of these problems

Balloon helium is 3% helium. So every 33 balloons is one Balloon worth of pure helium. No helium starts off pure. It all gets concentrated/separated to get that way. “Balloon grade” helium can be concentrated just fine and considering that thousands of those balloons are filled every day, it is a lot of wasted helium.

*I had my percentage swapped, it seems. Balloon helium is 97% helium.

balloon helium has some air in it, it’s still 90%+ helium, probably

One of the things I read said it has to be at least 93% to make balloons float.

i’ve took time to actually look up various manufacturers’ datasheets and it’s: range 50-99%, 95%, 97%, range 95-100%, 99%, unspecified or just data for pure helium. at this point i’m pretty sure there’s no such thing as “balloon gas manufacturer”, everyone buys 4N+ cryogenic helium and balloon gas consists of odds and ends that come from flushing piping and empty bottles with better stuff

skillissuer@discuss.tchncs.de on 02 Mar 2024 17:25 next collapse

how much do you need to float, if it’s helium then 1L lifts about 1g of mass, if it’s 50% helium 50% air it lifts 0.5g per liter, then it depends on how heavy balloon is in relation to its volume

kalkulat@lemmy.world on 04 Mar 2024 09:45 collapse

The balloon + helium has to be lighter than the (couple of liters of) air it displaces.

He Density (at STP) 0.1786 g/L

The density of air at sea level is about 1.2 g/L

Another interesting factoid about rare elements: Very little nickel is found in the Earth’s crust. Most nickel has arrived on Earth from meteors. Usually mixed with iron, which held-back the arrival of the iron-age.

What the fuck are you on about? Helium is an element. Doesn’t matter if it’s low purity it’s wasted and then gone. When the high purity stuff is gone we can’t be like “thank god we can purify the low wall quality stuff” when that’s gone too

It isn’t exactly wasted. Like you said, it’s an element. Short of any nuclear reactions, it won’t be destroyed (plus I’m not entirely clear if any useful reactions actually consume helium).

Helium in balloons is returning to the atmosphere. We can re harvest it if we want. While that sounds wasteful, it might actually be more efficient than trying to purify lower grade helium.

I’ll put it this way. If the helium in balloons could be easily purified to what they need for industrial uses, we wouldn’t be using helium in balloons. Purification industry would drive the price of it sky high.

EDIT: Ignore most of this, I didn’t do my due research.

Shteou@lemmy.world on 02 Mar 2024 20:32 next collapse

I won’t speak to the purification aspect (though I suspect purification is quite trivial), but helium released into the atmosphere is wasted. Saying it’s not destroyed is by the by, we aren’t going to recover it from space as it rapidly escapes the atmosphere.

Energy cannot be created nor destroyed; therefore it’s fine if I leave all my lights on 24/7 and use inefficient power hungry bulbs. It’s not a waste if it isn’t destroyed!

No. It wafts away into space. All the helium we find is a product of radioactive decay- alpha particles- which gets trapped underground. Once it’s released into the atmosphere, it is effectively gone.

helium just boils off in MRI/NMR machines, this is the major use of helium i think. if you could recycle that in machines that already are out there, that would solve lots of problems. there are newer systems that do not require cryogens or just require liquid nitrogen which is much cheaper and less energy intensive. these things use closed loop refrigeration, but in turn you need to supply them with power

Sounds like superconductor research could end up fixing that problem. Once we have a suitable conductor material, you no longer need to keep it that cool.

skillissuer@discuss.tchncs.de on 03 Mar 2024 11:53 collapse

not exactly, because if someone finds out that high temperature superconductor works even better at 4K, then it will be running at 4K, making entire thing more compact or allowing for higher fields

The helium used for balloons is not the same type of helium used in medical and scientific equipment.

Wdym? The only difference is the helium gas used in more serious applications is more pure. Its helium all the same.

Look up Helium-3 vs Helium-4, it most certainly is not “all the same”.

DrRatso@lemmy.ml on 03 Mar 2024 15:16 collapse

Helium-3 is not used in general applications, its uses are far more niche, it is much more rare than helium 4. For most applications, when we talk about helium being used we mean plain old helium-4. MRI machines and balloons both use helium-4.
