摘要

This study investigates the usability of marble wastes generated in the Emirdağ (Afyonkarahisar, Türkiye) region as alternative raw materials for lime production. Quarry sites exploiting predominantly Mesozoic grey to dark grey carbonate rocks around Alibeyce, Beyköy, and Bağlıca were selected, and representative waste materials were systematically characterized. The analytical framework combined petrographic and mineralogical examinations, geochemical analyses, stable isotope measurements, and lime suitability tests performed in accordance with Turkish Standards Institution (TS EN 459-2) procedures. Calcite was identified as the dominant mineral phase, accompanied locally by minor opaque constituents. Geochemical results indicate high CaO and very low impurity contents, whereas Sr is the most notable trace element. Calcination and post-calcination tests, including free CaO determination, loss on ignition, reactivity, color, chemical composition, and particle-size analyses, show that most samples possess favorable characteristics for the production of high-calcium lime. The results demonstrate that marble wastes from the study area represent a technically suitable and environmentally valuable industrial raw material.
