The Cinovec deposit, located in the Czech Republic is subject of a non-binding MoU with European Metals Holdings. Lithium in the deposit is primarily hosted by zinnwaldite, a lithium mica, however lithium potentially also occurs in other silicates, which, until now has not been recoverable. The Sileach process has the potential to improve the economics of the Cinovec project by recovering a significant portion …

Historic mining and exploration. The Zinnwald/Cínovec deposit is one of the most important greisen-type ore deposits of the Central European Variscan Orogen. It is not possible to reconstruct the exact date of the first mining activities, but it is estimated to be the end of the 13 th century (Schilka 1991). Starting from the first discovery, the main focus for around 400 years was the extraction of tin ore (cassiterite). …

mining, processing and energy requirements, lithium ores contribute only 15% of current lithium production (Roskill Information Services (2009)). As world lithium demand, driven primarily by increased pro-duction of batteries, is expected to grow about two fold in the next 10 years and may exceed supply by 2017, minerals get more attention as an alternative source of lithium to offset the ...
