Flotace grafitové suroviny

Abstract

This Diploma Thesis deals with laboratory comparing of floatability of graphite under specific condicions. On the graphite sample was compared efficiency of flotation reagents Flotalex Total Bio, Flotalex MR2 and Flotakol. Furthermore part of the sample was used for bacterial leaching. For this laboratory research was used a pure bacterial culture of Acidithiobacillus ferrooxidans. During and after bacterial leaching was the sample flotated and each fraction was tested for burnable substances content, which would indicate changes to pyrite content.
