    (2006) Fečko, Peter; Pečtová, Iva; Čablík, Vladimír; Riedlová, Silvie; Ovčaří, Pavla; Tora, Barbara
    The aim of this paper is to evaluate the suitability of a coal samples from different mines from Poland and Czech Republic for bacterial leaching. Laboratory research used a pure bacterial culture of Thiobacillus ferrooxidans. Were tested the samples from this localities: Mine Marcel, Mine Jankowice, Mine Staszic (Poland) and Mine Darkov and Mine Dukla (Czech Republic). The results showed that bacterial leaching was effective, with one month leaching time, when total desulphurization is from 38% to 72% and desulphurization of pyritic sulphur is from 60% to 82%. The paper describes changes of coal macerates after bacterial leaching.
