Abstract

The mechanical activation of α-spodumene in centrifugal planetary apparatuses changed the structure of the mineral and caused the cleavage of the Me-O (Me-Li, Al) bonds. Further treatment with acids and alkali led to the nearly complete transition of aluminum and lithium to the liquid phase. The alkaline decomposition of activated α-spodumene formed aluminate solutions, from which lithium aluminum hydroxide LiOH · 2Al(OH)3 · mH2O was precipitated.
