dc.description.abstract The content of sulphur in the combusted previous termcoalnext term belongs to the greatest environmental risks of the energy production in thermal power plants. There are various possibilities of sulphur separation from the previous termboiler coal.next term There were tested procedures of the previous termchemicalnext term extraction by ferric sulphate with the previous termbiological-chemicalnext term regeneration of the amortized leaching reagent using Acidithiobacillus ferrooxidans in the BACFOX method as well as the direct previous termbiological-chemicalnext term leaching by Acidithiobacillus ferrooxidans and Acidithiobacillus thiooxidans and as the mixed cultures exploitation. Obtained results confirmed the same efficiency of the sulphur previous termchemicalnext term extraction using the biologically reclaimed reagent. Maximal desulphurisation degree 84.68% was achieved in the direct previous termbiological-chemicalnext term sulphur leaching by the mixed cultures Acidithiobacillus ferrooxidans and Acidithiobacillus thiooxidans application. In the parallel were tested also methods of the previous termboiler coalnext term bioflotation using Acidithiobacillus thiooxidans as a pyritic sulphur depressor. In this method was used the biocatalytic acceleration of the pyrite oxidation. Thereby we suppressed the flotation of pyrite and the previous termcoalnext term cans flotate. The results follow that after one weak interaction between the bacteria and previous termcoalnext term mass, bacteria suppressed pyrite and after flotation the content of the previous termcoalnext term concentrate was higher. en
