structure which include zinnwaldite [2,9]. In the case of zinnwaldite (contrary to other lithionites), the most suitable method for its extraction seems to be the process of magnetic separation in some of the known types of magnetic separators. Zinnwaldite has significant magnetic properties due to a relatively high content of iron

The ZAG ( zinnwaldite-albite-granite ) was found up to a depth of 730 m. From 390 to 540 m major zones of alternating ZAG and porphyritic zinnwaldite-microgranite (PZM) occurred. Greisen type mineralization at the Zinnwald / Cínovec deposit is related to flat dipping, sheet-like greisen ore bodies and veins in the apical part of a ...
Magnetic separation is the process of separating components of mixtures by using magnets to attract magnetic materials. The process that is used for magnetic separation detaches non-magnetic material with those that are magnetic. This technique is useful for not all, ...
AN APPLICATION OF A MAGNETIC SEPARATION FOR LITHIC MICA EXTRACTION Jezerska, L.; Landecka, A.; Kratochvil, M.; Kubecka, J.; Tkacikova, L. Abstract: Lithium, the alkaline metal, causes a great excitement in scientific as well as in media scene. His lithic mineral zinnwaldite attracts great attention to a deposit in Cínovec in Ore Mountains.
