    Abstract:

    The paper describes selected rare earth elements (REE) which the European Union included in the list of critical raw materials in 2010. These elements have a wide range of potential uses, for example as phosphors in display and lighting technology, in ceramics, metallurgy and automobile industry. Due to increasing demand for REE waste treatment containing these metals is very important nowadays. The most appropriate method appears to be hydrometallurgical processing and leaching in acid solution. The work deals with the general characteristics of REE and studying the possibility of processing selected species of WEEE containing REE especially the fluorescent lamps. Moreover, the work presents some experimental results from leaching of demercurized powder from spent fluorescent lamps in sulfuric and hydrochloric acid medium.
