Possibilities of Magnetic Separation of Lithium Mica

Popis výsledku v původním jazyce

In recent years, Cínovec area in the Ore Mountains (Krušné hory) has been increasingly discussed in the Czech Republic. The location has been known for mineral resources over 650 years. Tin, silver or tungsten was gradually mined in the given locality. Lithium was a neglected element throughout the extraction because the using was minimal in those days. However, in recent years, it has rapidly changed with the advent of modern technologies in the electronics and automotive industry (lithium batteries and accumulators). The aim of this study was to obtain a concentrate of the highest possible quality with cost-effective lithium content. This task was carried out on the device using a magnetic field to capture magnetic particles from the entrance charge. The first task was to determine the detailed characteristics of the input material, using network analysis and X-ray - diffraction. The method of wet and dry magnetic separation on the prepared samples was also used. The results show that using magnetic separation, high quality concentrates with a pure metal over 1.4 % of Li can be obtained. The best option for our experiment seems to be the use of dry magnetic separation. Some concentrates contained considerable amounts of rubidium and cesium, which accompany Li in the mineral cinvaldit (0.9 % of Rb, 0.02 % of Cs).
