Greenland's harsh environment and lack of infrastructure have prevented rare earth mining

Greenland’s harsh environment, lack of key infrastructure and difficult geology have so far prevented anyone from building a mine to extract the sought-after rare earth elements that many high-tech products require. Even if President Donald Trump prevails in his effort to take control of the arctic island, those challenges won’t go away.

The main challenge to mine in Greenland is, “of course, the remoteness. Even in the south where it’s populated, there are few roads and no railways, so any mining venture would have to create these accessibilities,” said Diogo Rosa, an economic geology researcher at the Geological Survey of Denmark and Greenland. Power would also have to be generated locally, and expert manpower would have to be brought in.
Another concern is the prospect of mining rare earths in the fragile Arctic environment just as Greenland tries to build a thriving tourism industry, said Patrick Schröder, a senior fellow in the Environment and Society program at the Chatham House think-tank in London.

Besides the unforgiving climate that encases much of Greenland under layers of ice and freezes the northern fjords for much of the year, the rare earths found there tend to be encased in a complex type of rock called eudialyte, and no one has ever developed a profitable process to extract rare earths from that type of rock. Elsewhere, these elements are normally found in different rock formation called carbonatites, and there are proven methods to work with that.
