European Metals Holdings Limited (ASX & AIM: EMH) has received exceptional testwork results which confirm separation efficiency and capability of flotation of lithium-bearing zinnwaldite.
The updated flotation testwork recently undertaken at Nagrom Laboratories (Perth) has repeatedly reached >95% lithium recovery from flotation concentrates at target Li-grades and mass yield. Ongoing testwork to confirm the robust nature of the process and optimise the Definitive Feasibility Study (DFS) design has surpassed previous performance indicators.
Results from testing and optimisation of flotation for the concentration of zinnwaldite in fine ore has exceeded expectations and further demonstrated the potential for high overall lithium recoveries when combined with magnetic separation for the coarse particle size ranges.
Detailed information on the floatation testwork conducted on Cinovec zinnwaldite ore is provided at the end of this report.
The exceptional lithium extraction results are outstanding and further underline the commercial viability of operations at Cinovec,” European Metals Executive Chairman, Keith Coughlan, said.
“These results show repeatability of >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 of 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.”
