A ritkaföldfém-bányászat jelene és perspektívái a világban
Absztrakt
A felgyorsult digitalizáció és automatizáció korszakába lépve egyre nagyobb az igény a ritkaföldfémekre. Számos lelőhelyet tartanak számon, de kevés esetében történt meg az ásványvagyon felmérése. Elsősorban karbonatitokhoz és alkáli magmás tevékenységekhez köthetőek a legjobb minőségű telepek. Az utóbbi években megtörni látszik a kínai hegemónia mind a kitermelés, mind a készletek tekintetében. Egyre több ország folytat kiterjedt kutatásokat és jelenik meg a ritkaföldfémpiacon. Ezzel párhuzamosan Európa fáziskésésben próbálja behozni a lemaradását és felmérni a saját nyersanyag-potenciálját.
