Abstract
The aim of this work was apply 57Fe Transmission Mössbauer Spectroscopy at room temperature in order to study the occurrence of ironcontaining mineral phases in 1 feed coal 2 coal ash obtained in different stages of the ASTM D3174 standard method and 3 fly ash produced when coal is burned in the TERMOPAIPA IV thermal power plant localized in Boyacá Colombia According to obtained results we can conclude the occurrence of pyrite and jarosite in the feed coal Fe2+ and Fe3+ crystalline paramagnetic phases superparamagnetic hematite and hematite in coal ash Fe2+ and Fe3+ noncrystalline and crystalline phases magnetite and hematite in fly ash Precisely for a basic understanding this work discusses some the possible transformations that take place during coal combustion
