Why is it hard to dig and refine rare earths

 

To dig rare earths, you need to cut the whole area. Cut the stones apart and add them to the sulfuric acid hydrochloric acid

It's full of radioactive substances and all kinds of bad mercury and heavy metals

Separates dissolved in acid well. In this way, it increases purity by repeating it about 30 times over and over again

I can't put it in a drum because there are too many acid solutions left after use

So people who live near here are sickened by underground water in a chemical lake, and rare earth workers are sickened and killed before the age of 40

There is a lot of radioactive material and the nearby area becomes uninhabited

The river needs to be close because of the huge amount of water in this process, but if the water flows into the river from Lake Waste Chemical, everyone who lives in the river can die due to the radiation of heavy metals

Only China, which doesn't care if people die, can do this

Summary: Every time you make a rare earth, it produces more radioactivity than a rare earth

That's rare earth powder

I need to explain how that powder comes out

If I did Minecraft or StarCraft, I thought minerals would come out of the mine, but that's not it

It's not that rare earths come out of rare earth mines

It's just a stone

Picking a pick in a mine is called mining

It's that rock that comes out of the skylight

Anyway, if you send a rock to the ground, the mining is over and it starts to be a sun light

Sunkwang is just processing

There are rare earths mixed with the stones that came out after mining

The problem is that other things are mixed

There's valuable minerals, there's just rocks mixed in

Separate the rest of the rare earths from each other in various ways

I don't understand separation

It's similar to what you do in the salt farm

If salty seawater is dried in the sun, the water evaporates and only salt remains, right?

It's a similar way to blow away other things and leave only rare earths

When we separate rare earths, we use strong acid solutions

In short, I'm spraying Sejae

Rare earths don't melt even if you spray them, so spray the rare earths and melt everything else

If you repeat something similar like 20 questions, and there's only rare earths left

We're finally done mining and refining rare earths

There are two problems here

You just sprayed a strong acid solution to separate something that's not rare earth elements, right?

Then, we'll get two as a result

1. rare earths

2. Strong acid solution + rare earth residue minerals

Number 2 is the problem

Common sense doesn't think that's good for you

In fact, all mining industries are like that, but there is an additional reason why rare earths are a problem

Rare earth means "rare soil."

To put it the other way, there are more debris than rare earths

First of all, I need to use a strong acid solution more

There's more waste coming out, too

The problem is that this debris is also a very harmful substance

Rare earth minerals, or stones from rare earth mines, contain uranium and thorium in addition to rare earths (there are other harmful substances)

On the contrary, when you dig uranium and thorium, rare earths come out as waste

In summary, every time you dig rare earths, you get porridge made by mixing far more radiation and detergents than rare earths

It's hard to deal with this dead man

Create a large artificial lake near the mine and throw it away

Of course, it's bad for the environment, and the lake wall collapses,

It may contaminate groundwater or rivers

The city is famous for two things: one is Zelenskyy's hometown and the other is an iron mine

The powder from the iron mine turned the whole city red

This is a dam in Hungary that's holding dregs burst and hit the town

For this reason, not only rare earths but also mining itself is subject to avoidance
