Abstract

Im Auftrag von European Lithium wurde die Anwendbarkeit einer trockenen Aufbereitung für das Spodumenerz der Koralm in Kärnten/Österreich überprüft. Die dazu verwendete Methode war die Elektroscheidung. Es wurden ausschließlich Tests mit den Pegmatitdykes durchgeführt, welche dafür in zwei Kategorien unterteilt und separat getestet wurden. Die Elektroscheidungsversuche wurden an zwei unterschiedlichen Kornklassen durchgeführt. Die Kornklasse 315/60 µm wurde auf einem Freifallscheider und die Faktion
