Now, you've probably heard people 00:00
talking recently about rare earths, rare 00:01
earth elements. But you might be 00:03
wondering to yourself, well, what are 00:05
they? How much of a big deal are they? 00:06
And should we be worried about them? 00:08
Well, over the course of the next few 00:10
minutes, we're going to go through that. 00:11
We'll start with that question of what 00:12
are they? And, you know, do we actually 00:14
kind of encounter them? Do you encounter 00:16
them in your everyday life? The short 00:17
answer, spoiler, yes. This is the 00:19
periodic table. You might well recognize 00:21
it. Where are the rare earth elements? 00:23
Well, look, it's this kind of area here. 00:26
So, look at that. There there they all 00:28
are all lined up kind of obscure. You 00:30
know, no one's talking all that much 00:33
about scandium or itrium or neodymium or 00:35
at least until they were they were not 00:39
talking about it much until a few years 00:40
ago. But this is all really important 00:41
stuff. And the reason that rare earths 00:44
matter, it's not so much because of what 00:46
they do on their own. It's because of 00:48
what they do when combined with other 00:50
materials. So you add them to an alloy 00:52
and it makes things stronger. It makes 00:54
it more heat resistant. It makes magnets 00:56
more powerful. Let me just kind of give 00:58
you an example of that. I mean, so, so 00:59
three tangible places where you're going 01:01
to see quite a lot of rare earths. Um, 01:02
fighter jets, this is particularly the 01:05
kind of defense side of it. Fighter 01:06
jets, you're talking about kind of 418 01:07
kg in an F-35 fighter jet. Type 51 01:09
destroyer, 2.6 tons of rare earths uh in 01:13
them. Something like a Virginia class 01:16
submarine, 4.6 tons of rare earths in 01:18
there. Now, all of that seems kind of, 01:22
you know, obviously important but quite 01:24
abstract. But there's another place 01:26
where we all see it in our everyday 01:28
lives and that is magnets. So neodymium 01:29
when it's added to boron and iron is 01:33
basically the best magnet in the world. 01:35
I'll show you a kind of reason for that 01:37
in a moment. But um you might be 01:38
wondering so where is it in your life? 01:40
Well if you have something like this so 01:42
some earbuds you've got neodymium. 01:44
You're dependent on neodymium because 01:47
you need really powerful magnets to 01:49
create speakers that are so tiny tiny as 01:52
the ones in here. And also by the way 01:54
when I take this here are the little 01:56
things that wouldn't you wouldn't have 01:58
that without rare earth. When you close 01:59
that you get that satisfying snap that 02:01
is also neodymium iron boron magnets. So 02:03
rare earth may may seem abstract but 02:07
actually it's in all of our lives. Uh 02:09
and it's elsewhere as well basically 02:11
pretty much any electronic device uh 02:13
these days and you know in your car. So 02:14
in your car for instance think about 02:17
sitting in your car the seat controls. 02:19
So being able to lift that seat to move 02:21
that seat forward and backwards if it's 02:22
electronic. Well, that is a it's it's a 02:24
motor. It's a little rare earth motor 02:26
being able to raise electric windows and 02:28
close them. Again, that's rare earth 02:30
magnets going in there, making that 02:32
function. And airbags, there are even 02:33
rare earths in airbags as well. In other 02:36
words, if you can't get rare earths, 02:38
then you're in trouble. And it's not 02:40
just inside cars as well. I mean, think 02:42
about like a car factory. The motors 02:43
that go into robots, that's rare earths 02:45
as well. You need those really powerful 02:48
magnets to make them work. And it's not 02:50
just that as well as within EVs. Okay, 02:52
so this is an EV motor. You can see the 02:56
copper there. Those are the kind of 02:58
copper uh windings. But inside most EV 02:59
motors, you have a lot of magnets as 03:03
well. And those magnets are rare earth 03:04
magnets. So it's all invisible, but it's 03:07
really important. And when I talk about 03:10
those magnets, just give you a sense of 03:12
why this is kind of important. What this 03:13
is showing you. So, the higher these 03:16
bars are, the more powerful, the more 03:18
magnetic power you're getting from 03:19
different types of magnets. And you've 03:21
got a range of different kind of 03:22
elements and compounds uh and in recipes 03:24
for magnets there. These are 03:27
conventional magnets. Now, look at rare 03:28
earth magnets. Just look at how much 03:32
more powerful they are than the other 03:34
type. And that's the point. Magnets are 03:36
incredibly important for any kind of 03:38
motion, for any speakers, for 03:40
microphones, for anything else. Uh and 03:42
we need quite a lot of them. But 03:45
actually the scale of what we're talking 03:47
about is not enormous. You only need 03:48
quite a small amount of rare earths to 03:50
make something function really well. And 03:52
another good example of that is consider 03:54
a jet engine. So the blades in a jet 03:56
engine, they need to function at a 03:58
temperature that is higher than the 04:01
metal's melting point. If you can get 04:03
that into your head. Um, and in order to 04:05
do that, they need what's known as anria 04:07
stabilized zuconia uh film on the 04:10
outside. And that enables them not to 04:13
melt. So no rare earths and itrium is a 04:15
rare earth. No rare earths and you just 04:18
don't have jet engines, at least modern 04:20
jet engines. So this is incredibly 04:22
essential. It's it's part of the bedrock 04:24
of how we make civilization work these 04:26
days. And if you're looking at just what 04:29
the functions of these rare earths are. 04:31
So so we talked about jet engines a 04:33
moment ago. That would come in the the 04:35
metallergy section of things. There's, 04:36
you know, glass polishing, ceramics, 04:38
catalysts as well. So it goes into 04:39
catalytic converters. But magnets is by 04:41
far and away. This is just looking at 04:44
the volume of rare earths coming out out 04:46
of the ground. Magnets is by far in the 04:47
way the biggest and actually when you 04:49
look at the value so the amount that 04:50
people are spending on rare earths 04:52
across the uh the planet the majority of 04:54
that is magnets. So it's magnets that 04:57
are going into motors for the most place 04:59
uh as well as things like speakers and 05:01
airpods and so on. And here's where the 05:03
political side of things comes in. 05:06
Because when you're looking at where 05:08
these rare earths are coming out of the 05:09
ground, the vast majority come out of 05:11
the ground in China. 69% of the total uh 05:14
of of the volume mined out of the 05:18
ground, the oxides uh comes from China. 05:20
And actually that's 69%. But then when 05:22
you consider the processing, so the 05:24
post-processing stuff, because most of 05:27
most of the the rare earths are then 05:29
turned into products in China, actually 05:30
91% of global supplies is Chinese. And 05:33
that's not just the case, by the way, 05:37
for rare earth. Look at things like 05:38
copper. Look at lithium, manganese, 05:40
graphite, cobalt. China is really 05:42
dominant in all of this. They have 05:44
decided years ago that they wanted to be 05:45
dominant in these supply chains. and not 05:47
just the supply chains but also making 05:49
the stuff afterwards. So graphite's 05:51
there. They also want to be the dominant 05:53
player when it comes to making the 05:55
anodess that go into batteries. That's 05:56
why they're in graphite, cobalt for 05:57
batteries as well. Manganesees too, 05:59
lithium, copper as well. So that is, you 06:01
know, it's part of this bigger story 06:04
about Chinese dominance. But here's 06:05
where there are a few kind of myths that 06:07
are worth busting. The first of them is 06:08
that despite the name, rare earths 06:10
aren't actually that rare. So there's 06:13
quite a lot of these elements in bits of 06:15
the ground. You know, actually if you if 06:18
you pull a chunk of rock of earth out of 06:19
the ground, you will find some rare 06:21
earth elements in there, albeit in small 06:22
quantities. But even when you look at 06:24
decent ores, well, China, yes, has a 06:26
lot, 44 million tons, but there's a lot 06:28
of it also in Brazil, and they're not 06:31
really mining much of it at the moment 06:32
in Brazil. Uh there's a lot in India, 06:33
there's a lot in Australia as well, 6 06:36
million tons in Australia. Now, most of 06:37
those countries aren't doing all that 06:40
much in the way of mining. Most of it's 06:41
happening in China. Why is that? Well, 06:43
let's just kind of zoom in and focus on 06:46
the biggest of all the mines in China. 06:49
So, that's Bayan Obo. It's just in kind 06:51
of Inner Mongolia uh there in China. And 06:53
have a look at this mine. Okay, we're 06:55
going to kind of zoom out uh or zoom in 06:57
there and have a look at how much this 06:59
mine has expanded in recent years. And 07:01
you're going to notice other things as 07:04
well. So, this is the primary mining 07:05
site. This is back in 2001. 07:06
And look at what happened in the 07:09
intervening years. Okay. So, you can see 07:10
2006, you've got these excavations 07:13
happening over there to the west. And 07:15
now, keep your eye on this area here. 07:18
And we'll zoom on. We'll kind of fast 07:20
forward to the present day. Look at 07:22
that. So, this has been an enormous 07:24
expansion. And you have a whole new 07:27
mining area over there. This place is 07:28
pumping out basically most of the 07:31
world's rare earths in China. And the 07:32
other thing you'll probably have noticed 07:35
looking at it is look at all of these 07:36
tailing dams where the waste is being 07:38
disposed of. Producing rare earths is a 07:40
really dirty process. It is really 07:44
dirty. It's really hard to do basically 07:46
because you're having to do about 100 07:48
different processes to go from the ore 07:49
to that final metal that you're turning 07:51
into magnets. And to give you a sense of 07:54
that, okay, so this is showing you the 07:56
amount of carbon emissions from various 07:57
different metal processing. And you 07:59
you're probably familiar with the fact 08:01
that making steel is really carbon 08:02
intensive. You know, think of all those 08:04
blast furnaces. Well, that's steel 08:05
there. It's actually quite small in 08:07
comparison with other things like copper 08:09
and nickel and aluminium at least per 08:11
weight uh per amount of kilogram that 08:13
you're producing. But now compare all of 08:16
that to neodymium which is that that 08:18
kind of key rare earth in all of those 08:20
magnets. And look at that. Boy, I mean 08:22
there is more carbon emissions that 08:25
coming per kilogram of rare earths than 08:27
any other metal in the world. It is 08:29
really dirty to produce. And one of the 08:31
upshots of that is everyone else out 08:33
there with the you know all of their 08:36
carbon targets has said well we just 08:38
don't want to do this in our countries. 08:40
So now it is mostly happening in China 08:42
and it's happening at scale as you saw a 08:44
moment ago and it's happening at such a 08:46
scale that China is able to produce 08:48
these things at a far lower cost than 08:50
almost anyone else in the world. Well 08:52
actually clear by far and away anyone 08:54
else in the world. This is just showing 08:56
you a couple of examples. Dsposium and 08:57
turbium two rare earths rare earth 08:58
elements. Look at how much Chinese 09:01
prices are. And now let's compare that 09:03
with European prices because there are 09:05
some producers outside uh of China. But 09:06
just look at how much more expensive it 09:10
is to get European rare earths versus 09:11
the Chinese stuff. And that's the issue. 09:14
Stuff like those earbuds are cheap right 09:17
now because you can get cheap Chinese 09:20
rare earths but is produced with all 09:22
these carbon emissions at the same time. 09:23
But people aren't thinking about all 09:26
this. They are thinking about it a bit 09:27
more now though because China has 09:29
basically said we are going to impose 09:30
restrictions on the rare earths coming 09:32
out of China. You're going to have to 09:33
sign up to get licenses. And as a 09:35
result, Donald Trump has said well no 09:37
not not happy with that. I'm going to 09:39
raise tariffs on you again. And so this 09:41
is where the the latest kind of state of 09:43
play this ever moving map of tariffs uh 09:45
that the US is imposing on other 09:47
countries around the world. You'll 09:49
recall not re not that long ago uh it 09:50
said there were going to be secondary 09:53
tariffs on India for all of the the 09:54
refining it's doing of Russian gas uh 09:56
Russian oil rather. Now Donald Trump has 09:58
said there's going to be an extra 100% 10:00
tariff on China. We'll have to see 10:02
whether that eventually happens. But 10:05
this trade war we've been talking about 10:07
a lot recently seems like it might be 10:08
back on again. But finally, I just want 10:10
to kind of raise that question. So, 10:13
China is doing that with rare earths. 10:14
It's limiting this critical ingredient 10:16
that no one else is producing. And that 10:18
raises a question. Is there anything 10:21
similar that the US could do? And here's 10:22
something interesting. Okay, so we'll go 10:25
back to that map. Okay, so there's 10:26
China. That's where the rare earths are. 10:28
Swing across to the US and there's 10:29
somewhere called Spruce Pine. It's 10:33
another mining site. It's in North 10:34
Carolina. They don't produce rare earths 10:36
here, but they produce something perhaps 10:38
even more special in there. They are 10:40
mining what's known as ultra high purity 10:42
quartz. And this is a type of basically 10:45
sand, really pure sand that you need to 10:48
make the wafers that go into silicon 10:51
chips. If you don't have this place, you 10:54
don't have silicon chips or solar 10:56
panels. So perhaps one thing, who knows 10:58
that the US may end up thinking about is 11:02
whether it can do the same thing that 11:04
China is doing with its mine on the 11:06
other side of the world with this 11:07
critical ingredient. But who knows? What 11:09
we do know is that we're on a roller 11:12
coaster and there's going to be more of 11:14
this stuff in the coming months. 11:16

Now, you've probably heard people
talking recently about rare earths, rare
earth elements. But you might be
wondering to yourself, well, what are

And should we be worried about them?
Well, over the course of the next few

incredibly important for any kind of

we need quite a lot of them. But
actually the scale of what we're talking
about is not enormous. You only need
quite a small amount of rare earths to
make something function really well. And
another good example of that is consider
a jet engine. So the blades in a jet

those countries aren't doing all that

happening in China. Why is that? Well,
let's just kind of zoom in and focus on
the biggest of all the mines in China.
So, that's Bayan Obo. It's just in kind
of Inner Mongolia uh there in China. And
have a look at this mine. Okay, we're
going to kind of zoom out uh or zoom in
there and have a look at how much this
mine has expanded in recent years. And
you're going to notice other things as

now, keep your eye on this area here.
And we'll zoom on. We'll kind of fast

mining area over there. This place is
pumping out basically most of the

tailing dams where the waste is being

different metal processing. And you
you're probably familiar with the fact
that making steel is really carbon
intensive. You know, think of all those
blast furnaces. Well, that's steel
there. It's actually quite small in
comparison with other things like copper
and nickel and aluminium at least per
weight uh per amount of kilogram that
you're producing. But now compare all of
that to neodymium which is that that
kind of key rare earth in all of those
magnets. And look at that. Boy, I mean
there is more carbon emissions that
coming per kilogram of rare earths than
any other metal in the world. It is
really dirty to produce. And one of the
upshots of that is everyone else out
there with the you know all of their
carbon targets has said well we just
don't want to do this in our countries.
So now it is mostly happening in China
and it's happening at scale as you saw a
moment ago and it's happening at such a
scale that China is able to produce
these things at a far lower cost than
almost anyone else in the world. Well
actually clear by far and away anyone
else in the world. This is just showing
you a couple of examples. Dsposium and
turbium two rare earths rare earth
elements. Look at how much Chinese
prices are. And now let's compare that
with European prices because there are
some producers outside uh of China. But
just look at how much more expensive it
is to get European rare earths versus
the Chinese stuff. And that's the issue.
Stuff like those earbuds are cheap right
now because you can get cheap Chinese
rare earths but is produced with all
these carbon emissions at the same time.
But people aren't thinking about all
this. They are thinking about it a bit
more now though because China has
basically said we are going to impose
restrictions on the rare earths coming
out of China. You're going to have to
sign up to get licenses. And as a
result, Donald Trump has said well no
not not happy with that. I'm going to
raise tariffs on you again. And so this
is where the the latest kind of state of
play this ever moving map of tariffs uh
that the US is imposing on other
countries around the world. You'll
recall not re not that long ago uh it
said there were going to be secondary
tariffs on India for all of the the
refining it's doing of Russian gas uh
Russian oil rather. Now Donald Trump has
said there's going to be an extra 100%
tariff on China. We'll have to see
whether that eventually happens. But
this trade war we've been talking about
a lot recently seems like it might be
back on again. But finally, I just want
to kind of raise that question. So,
China is doing that with rare earths.
It's limiting this critical ingredient
that no one else is producing. And that
raises a question. Is there anything
similar that the US could do? And here's
something interesting. Okay, so we'll go
back to that map. Okay, so there's
China. That's where the rare earths are.
Swing across to the US and there's
somewhere called Spruce Pine. It's
another mining site. It's in North
Carolina. They don't produce rare earths
here, but they produce something perhaps
even more special in there. They are
mining what's known as ultra high purity
quartz. And this is a type of basically
sand, really pure sand that you need to
make the wafers that go into silicon
chips. If you don't have this place, you
don't have silicon chips or solar
panels. So perhaps one thing, who knows
that the US may end up thinking about is
whether it can do the same thing that
China is doing with its mine on the
other side of the world with this
critical ingredient. But who knows? What
we do know is that we're on a roller
coaster and there's going to be more of
this stuff in the coming months.
