The Power Plant Ostroleka is one of many in Poland, which is coal-fired. Fly ash, as is well known, are combustion by-products, which are mineral residue from burning coal. Their phase composition depends mainly on the quality of fuel (coal) and combustion conditions. In the mineral composition of the examined ashes one has identified minerals such as: glass, quartz, mullite, spinels, hematite. Spinels present in the fly ash can be a source of some metals, and due to the magnetic properties of some of them, are ea...

The Rare Earth Elements (REE) have been classified as resources critical for the European Union and divided into: light rare earth elements and heavy rare earth elements. The demand for REE is constantly increasing, which is connected with the wide range of their applications. The article presents the results of research conducted to determine the concentration of Rare Earth Elements in fly ashes obtained from the combustion of coal at the Rybnik Power Plant. The concentrations were measured using the ICP-MS and S...

The Power Plant Rybnik (Elektrownia Rybnik) is one of many in Poland, which is coal-fired. Fly ash, as is well known, are combustion by-products, which are mineral residue from burning coal. Their phase composition depends mainly on the quality of fuel (coal) and combustion conditions. In the mineral composition of the examined ashes one has identified minerals such as: glaze, quartz, mullite, spinels, hematite, and unburnt coal. Spinels present in the fly ash can be a source of some metals, and due to the magneti...
