TEVLiS
Technologies for extracting and processing lithium mica from slag heaps in the Ore Mountains
Time span
From 01.10.2022 to 30.09.2025
Abbreviation
TEVLiS
Project type
Technologies for extracting and processing lithium mica from slag heaps in the Ore Mountains
At the beginning of the project, the tailings body is examined and evaluated with regard to its geological and mineralogical properties. The surface outcrops required for this also provide the opportunity for sampling, which forms the basis for geochemical and geotechnical investigations as well as for the necessary processing tests. The primary useful minerals zinnwaldite (Li-mica) and cassiterite are separated from the finest-grained processing residues (< 40 μm) by optimizing known processing methods. In cooperation with partners from industry and science, the use of the silicate residues as potential aggregates for building materials is being investigated. This concept is intended to achieve maximum minimization of the deposited masses and the aftercare load while at the same time refinancing the remediation of the contaminated site. The associated complete dismantling of the tailings will be assessed as part of the project in terms of its expected political and social resonance. The mica concentrates produced by the processing will be processed into marketable Li products in a laboratory test and the result will be assessed in terms of its economic viability.
The implementation of the project creates a further basis for the development of the regionally based project partners as suppliers of AI processes, extraction, preparation and processing technologies and contributes to the supply of important raw materials.
The resulting technology concept should be marketable worldwide and serve as a template for processing other low-grade ores.
