Mikroskopické pozorování změn v průběhu bakteriálního loužení uhlí

Abstract

The Graduation thesis is devoted to problems of pyritic grains ablation, which are disseminated in coal, by the help of bacterial leaching. Pyrite in coal presents one from sources of sulfur, whose combustion rise sulphur oxides SO2 and SO3. I used bacterial culture of Acidithiobacillus ferrooxidans to pyrite ablation in my thesis. In theoretic parts of Graduation thesis devote I to the description of bacterial leaching principles, acquaintance with Acidithiobacillus ferrooxidans, coal mass analysis, microscopy theory, samples preparation and parameters, which impacts usability of the technology. The aims of Graduation thesis are experimental data evaluation, pyrite nuggets changes appreciation and estimation of usability, foreground. bacterial leaching effectivity.
