Mit Drohnen auf Spurensuche

Neuer Ansatz für die Erkundung von Seltenen Erden

(PresseBox) (Freiberg, )
Seltene Erden sind wichtige Rohstoffe für die Energiewende, die Elektromobilität und Zukunftstechnologien. Der Einsatz von Drohnen bietet eine einzigartige Möglichkeit, Seltene Erden auch in ökologisch sensiblen und schwer zugänglichen Gebieten schnell zu erkunden. Wissenschaftler*innen des Helmholtz-Instituts Freiberg für Ressourcentechnologie (HIF) am Helmholtz-Zentrum Dresden-Rossendorf (HZDR) haben nun zum ersten Mal Seltene Erden in ariden und subarktischen Umgebungen mithilfe von Drohnen-basierten Hyperspektraldaten direkt identifiziert und kartiert. Ihre neuartige Nachweismethode wurde in Scientific Reports (DOI: 10.1038/s41598-020-74422-0) veröffentlicht.

Mineralische Ressourcen werden immer knapper und sind schwerer zu finden. Gleichzeitig benötigen wir jedoch Rohstoffe, insbesondere Seltene Erden, um unser Ziel einer „grüneren“ Gesellschaft zu erreichen.
