It's a journey to the center of the rare earths discovered in Sweden

Your skin becomes noticeably drier, your ears pop and it's hard to shake a feeling of isolation as the truck twists and turns on the darkened road, guided only by reflectors on the tunnel's reinforced gray, stone walls.
When you finally reach the bottom, more than 4,000 feet beneath Earth's surface, you discover a complex of brightly lit offices, a cafeteria and even a car wash.
The state-owned LKAB mine, which sits 125 miles north of the Arctic Circle, is one of the world's largest sources of iron ore, used for making steel.

Mixed in with the iron ore were rare earths — raw materials that are used to power motors in wind turbines, electric vehicles and a range of other products and that are critical for the transition to clean energy. The company said it deposit of rare-earth metals in Europe.
, which dominates the world's supply and processing of key metals and minerals, including rare earths. It also comes as European countries seek to switch from fossil fuels to renewable energy sources like wind and solar, using technologies that rely on rare earths.Notes

Sweden has known it has rare earths for a while
LKAB was aware of some rare-earth deposits in Sweden as far back as the 1960s as it was mining iron ore, says Laura Lauri, a field exploration manager at the mine.
"We knew that there was something out there, but we didn't know how much and at what depth and things like this," she says. Three years ago, they started taking a closer look, and the results were good. The company estimates there are (about 1.43 million U.S. tons) of rare earths at the deposit.
Exploration is a long process. Just getting to the Per Geijer deposit is a major undertaking. In a small office in the vast underground complex, Jim Lidstrom heads up the team digging 5 miles of tunnels toward the rare earths. He says they clear just 15 feet a day.

"My guess would be around maybe six to seven years ... until the exploration tunnel is done."
"It's been a ... harsh reminder to choose your friends wisely," she says. "I would say that Sweden, we have really ... drawn a very tough lesson in terms of being so highly dependent off of Russia."
Dependence on China is also a concern for Sweden, especially the Asian nation's grip on critical metals and minerals such as the rare earths. Like the rest of the, Sweden gets nearly all its rare-earth supply from China.

"And China is known for using their raw materials, for instance in geopolitical challenges, if you like ... as a weapon."

China also dominates rare-earth processing, but Ingvald says there's movement to increase processing capacity in Europe.
"For instance, LKAB has bought into a company in Norway who are going to do this processing of those minerals," she says. "So we keep the value chain in Europe."
But processing can be , and there's a lengthy permitting procedure that also considers the impact of mining and processing on Sweden's vast Indigenous lands.
