Lignite and other types of coal are formed as result of different chemical and biological transformations of ligneous and plant materials lacking oxygen. During the coal use for energy production , there are mineralogical remains in the form of ashes, which have different physical, chemical, mineralogical and morphological properties, which largely depend on the type of coal used, and technology in its combustion. This type of ashes is presented in thermal power plants in the form of dust or fly ash and inorganic ...

The main purpose of this work was to analyze possibilities for application of lignite byproducts- fly ash from Kosova Power Plants in other industry branches and for filling of old underground mines and see the positive impact in environmental protection. The Kosova lignite-fired power generation industry produces millions tones of fly ash each year. Only small amount of this fly ash is used, with most being considered a waste. This waste must be disposed of in an environmentally acceptable way at a cost which is ...
