 abstract={Fly ashes from the combustion of lignite coal are suitable materials for the creation of suspensions in which CO2 is bound by mineral carbonation. Considering their limited economic uses, mineral sequestration, as a stage of the CCS technology in lignite coal power plants, can be a way of recycling them. Mineral sequestration of CO2 was researched using fly ashes from the combustion of lignite coal in the Pątnów power plant, distinguished by a high content of CaO and free CaO. Research into phase composition confirmed the process of carbonation of the whole calcium hydroxide contained in pure suspensions. The degree of CO2 binding was determined on the basis of thermogravimetric analysis. A rise in the content of CaCO3 was found in the suspensions after subjecting them to the effects of carbon dioxide. Following carbonation the pH is lowered. A reduction in the leaching of all pollutants was discovered in the studied ashes. The results obtained were compared to earlier research of ashes from the same power plant but with a different chemical composition. Research confirmed that water suspensions of ashes from the combustion of lignite coal in the Pątnów power plant are distinguished for a high degree of carbonation.},
