Bacterial desulphurization of coal from mine CSA Most

摘要

The objective of the paper was application of bacterial leaching on 3 brown coal samples from bore S 187 (CV) from locality Mine CSA Most. Based on the results of bacterial leaching and petrologic analyses of the given samples, it is possible to state that the individual samples are very similar, they contain significant shares of clay materials and pyrite is predominantly represented in a framboidal form, which intergrowths into a massive form. Applying bacterial leaching it is possible to remove from 24 to 40% of total sulphur and from 20 to 37% of pyritic sulphur from the coals.
