Geologists studied Estonian phosphorite.
They found that phosphorite can be used to make chemicals and metals.
But currently, phosphorite mining is not profitable.
Europe buys a lot of phosphorite.
Most of it comes from Morocco and Russia.
Estonia has a lot of phosphorite, mainly in Toolse.
Toolse phosphorite is by the sea.
Mining would be easier there.
But there is little phosphorite there.
Estonian phosphorite is pure.
But it needs further purification.
This makes Estonian phosphorite more expensive.
Geologists also tried to find metals.
There were few metals.
Processing them is too expensive.
The whole process would cost a lot.
The price of phosphorite would need to rise.
Mining would affect the environment.
Water levels could drop.
In Rakvere, water would drop less.
A big problem is waste.
Waste processing is difficult.
The study cost 5 million.
Now we know that phosphorite can be used.
But currently, it is not profitable.
The phosphorite will remain underground.
Geologists will continue their work.
They are looking for opportunities to use Estonia's mineral resources.
