Significant reserves of Li are also represented in waste from the former mining and processing of Sn-W ores in the Krušné hory region, containing about 0.2 % Li. The world consumption of lithium is estimated 6 kt/year and a gradual increase is expected, as well as an increase of the price.

Processing of zinnwaldite waste to obtain Li2CO3

Jun 01, 2010 In this study, Li 2 CO 3 was extracted from a zinnwaldite concentrate with 1.21% Li and 0.84% Rb prepared from zinnwaldite wastes (0.21% Li, 0.20% Rb). These wastes originated from dressing of Sn–W ores, which were mined in the Czech Republic in the past. Processing of the zinnwaldite concentrate consisted of roasting the concentrate with CaCO 3 followed by water

Sep 10, 2013 A zinnwaldite concentrate containing 1.29% of Li and 0.94% of Rb was prepared by dry magnetic separation of the lithium-rich sand, the by-product after Sn–W ore mining in the Czech Republic. According to the results of XRD analysis, the concentrate consisted of two main phases: dominant zinnwaldite KLiFe 2 + Al(AlSi 3 )O 10 (F,OH) 2 and minor

Lithium Wikipedia

Lithium (from Greek: λίθος, romanized: lithos, lit. 'stone') is a chemical element with the symbol Li and atomic number 3. It is a soft, silvery-white alkali metal.Under standard conditions, it is the lightest metal and the lightest solid element.Like all alkali metals, lithium is highly reactive and flammable, and must be stored in mineral oil.
