Side products from power industry as the raw material base for the future
Marko, Michal ; Kalina, Lukáš (referee) ; Opravil, Tomáš (advisor)
This work reacts to the worldwide problem related to looking for alternative sources of raw materials. The work deals with analyzing samples of high temperature and fluid fly ashes produced by power plants in the Czech Republic, followed by experimental verification of possibilities to separate some desired components. Based on the elemental and phase compositions, the possibility of aluminum, titanium, and iron extraction to sulfuric acid solution and subsequent selective precipitation using suitable separeation methods was designed and tested in a laboratory scale. Separation of selected elements from the fly ash matrix was carried out at room temperature and then at the boiling point of the used solvent.
