N2 - 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 magnetic properties of some of them, are easy to separate from the ashes. The paper presents the variation of the chemical composition of spinels found in fly ash from the Power Plant Rybnik (Poland). As the test results indicate, representatives of this group of minerals in the system: (i) Fe2+/(Mg2++Fe2+) – Fe3+/(Al3++Fe3+) are: magnesioferrite, magnetite, ferrian pleonaste and hercynite, (ii) Cr – Al – Fe3+: Al-magnetite i Fe-spinels, (iii) Fe3+ – Al3+ – Cr3+: magnetite and hercynite, (iv) rutile – hematite – wustite: spinels similar to the composition of magnetite.
