European Metals (ASX:EMH) has achieved ‘exceptional’ testwork results that confirm the separation efficiency and capability of flotation of lithium-bearing zinnwaldite from its Cinovec Lithium-Tin Project in the Czech Republic.
The company says the updated flotation testwork recently undertaken at Nagrom Laboratories in Perth has repeatedly reached more than 95% lithium recovery from flotation concentrates at target lithium grades and mass yield.
Additionally, ongoing testwork to confirm the ‘robust’ nature of the process and optimise the Definitive Feasibility Study (DFS) design has surpassed previous performance indicators.
European Metals says the results from the testing and optimisation of flotation for the concentration of zinnwaldite in fine ore have exceeded expectations and further demonstrated the potential for ‘high’ overall lithium recoveries when combined with magnetic separation for the coarse particle size ranges.
Commenting on the recent testwork, European Metals Executive Chairman Keith Coughlan says: “The exceptional lithium extraction results are outstanding and further underline the commercial viability of operations at Cinovec.
These results show repeatability of over 95% lithium recovery at neutral pH and confirm both capex and opex reductions, demonstrating the strong operational viability of the FECAB plant.
We look forward to further results from the ongoing optimisation work as part of the DFS. The neutral pH of the flotation further enhances the already-strong ESG credentials of the Cinovec Project, particularly when compared to the acid flotation used on micas elsewhere around the globe.

We expect the current testwork to be completed by the end of June and will publish the full results.”
European Metals reports the DFS remains on track to be completed in Q4 2023.
European Metals is a mineral exploration and development company focused on advancing the Cinovec Lithium-Tin Project in the Czech Republic.
The Cinovec Project is held by joint venture (JV) company Geomet, in which European Metals and integrated Czech energy group CEZ hold a 49% and 51% interest, respectively. The project hosts a total mineral resource of 53.3 million tonnes @ 0.48% Li2O and 0.08% Sn.
